polypropylene (PP) random copolymer
polypropylene (PP) random copolymer is polypropylene (PP) types, it polymer/macromolecule basic structure use add different types type mono separation add modified. ethylene is most commonly used mono 体, it polypropylene (PP) material property 质 改变. and PP homopolymer versus ratio, random copolymer optical property can ( increase transparent degree decrease/reduce 浊雾), improve/increase impact resistant property can, increase property, reduce temperature degree, from reduce hot temperature degree; meanwhile in chemical stability property, water 蒸汽隔离 property can and device 官感觉 property can ( low odor and 味道)方面 and homopolymer basic same.
development will transparent degree and impact strong/high degree combined PP random copolymer, used for blow molding, injection molding, film and sheet/slice pressure processing field/area, as food packaging materials, packaging materials and day 常消费 product.
chemical
PP random copolymer generally has 1- 7%( weight ) ethylene separation and 99? 93%( weight ) propylene separation 子. in polymer upper, ethylene separation random 则 插 in propylene separation in 间. in this type of random or statistics copolymer in, large more 数( usually 75%) ethylene is mono separation 子插入 methods combined 进, 叫做X3基团(三 连续 ethylene [CH2]依次排列 in upper ), this also can formed is ethylene separation in propylene separation in 间.
另 has 25% ethylene is more separation 子插入 methods combined 进主链, also 叫X5基团, is has 5 连续 亚甲基团(两 ethylene separation 子一起插 in propylene separation in 间). very difficult X5 and more high 基团如X7, X9 and other add separation. 鉴于此, XS and more high ethylene content statistics is >X3%.
random degree ratio value X3/X5 can 测定. 当X3 above percentage very large 时, will significantly reduce copolymer crystallization degree, this for random copolymer most property can effect/influence very large. copolymer in high content ethylene for polymer crystallization degree effect/influence, similar high random polypropylene (PP) content function.
random PP copolymer different homopolymer, is random polymer in ethylene separation retardant polymer separation crystallization type 排列. copolymer crystallization degree reduce material property 质 改变: random copolymer and PP homopolymer versus ratio rigid degree reduce, impact resistant property can improve/increase, transparent degree more good. ethylene copolymer also has relatively low temperature degree, this formed it in certain application advantages.
random copolymer has relatively more can material and random PP, and ethylene content high more polymer 链. this type of relatively high can material content, different polymerization process, different degree in has product copolymer material in, in meet/satisfy food tube/pipe 理局( FDA ) about/regarding food contact upper formed difficult.
manufacturing methods
ethylene / propylene random copolymer is ethylene separation and propylene separation meanwhile polymerization reaction made, use reaction device and production PP homopolymer 一样. ethylene separation ratio propylene separation small, reaction fast 于( reaction active property 约十倍) propylene. this make catalytic agent 立体定 toward property decrease low active property increase large, from 而导致 random polypropylene (PP) formed amount increase more. is decrease/reduce this type of random material formed, need reduce reaction temperature degree, from reduce catalytic agent active property, decrease/reduce most material in random 异构体 content, to types tool has relatively property can product.
ethylene content high (>3%) random copolymer in production process in 处理起 comparison difficult, very difficult in dilute agent in polymerization reaction, is reaction grade product ( random polypropylene (PP) and ethylene amount very high copolymer ) can solvent 于己烷. this in liquid propylene polymerization reaction is 一样, tube/pipe solvent understanding degree relatively low. dilute process production a large amount of product, must in again ring stage/phase separation 离出, this increase production cost, however can to combined a small amount of can solvent separation relatively polymer. in polymerization process in, this 杂质会留 in polymer in, in thin sheet/slice material belt/tape 麻烦. but also, most copolymer product in has relatively more can solvent property 杂质. use has machine solvent agent 进行二次清洗, can remove large separation 杂质, also improve/increase copolymer production cost. generally, material content high 时, thin sheet/slice random copolymer relatively viscous, ethylene content high 于3.5%( weight )时, this issues more 突出.
处理 issues increase more, and relatively low reaction device temperature degree random copolymer relatively low production speed degree. but also random copolymer production cycle usually very short. this factors make random copolymer production cost high homopolymer, for ethylene content high random copolymer more is 如此.
copolymer melting point reduce and ethylene content related. 据报导, ethylene content is 7%时, copolymer melting point low 达152°F. X3 content for copolymer melting point effect/influence ratio and more high content effect/influence more large. it also 取决于 catalytic agent 本身, and its 以X3基团代替以X5基团结 combined ethylene can force.

PP copolymer material molecular weight for rigid property effect/influence 不如PP homopolymer large. belt/tape 切口 悬臂梁式 impact strong/high degree generally in 0.8~1.4英尺?磅/英寸 scope/range inner.
chemical resistance can: random PP copolymer for acid. alkali, alcohol, low carbon hydrogen combined material solvent agent and many has machine chemical product function has very strong/high resistant force. room temperature lower, PP copolymer basic solvent large more has machine solvent agent. but also, 当暴露 in 肥皂, alkali liquid. water property agent and alcohol type in 时, it 们不象 its it many polymer that 样会发生 ring force fracture loss bad. and certain chemical product 接触时, especially is liquid 体烃. chlorine has machine material and strong/high oxidation agent, can surface cracks or solvent 胀. non property combined material generally ratio property combined material more easy is polypropylene (PP) absorption.
retardant property can: PP copolymer and homopolymer has very low water 蒸汽渗透 rate (0.5克/ milli rise /100平方英寸/24 small 时). this property can through toward add 以改进. tensile blow molding type polypropylene (PP) bottle already resistant water 蒸汽渗透 property can 改进至0.3, oxygen gas rate to 2500.
electrical property can: generally, polypropylene (PP) has very good electrical property can, 包括: high electrical strong/high degree, low dielectric constant and low loss consumption 因子; however, power/electricity application generally selection homopolymer.
applications
random copolymer type polypropylene (PP) main/primary used for film, blow molding and injection molding and other requirements high transparency degree combined. ethylene content relatively high copolymer, due to 熔接起始 temperature degree relatively low 而广泛 used as extrusion film structure 特殊密封层.
poly 邻苯二酰 amine
poly 邻苯二酰 amine (简称PPA) resin is for 苯二甲 acid or 邻苯二甲 acid is raw materials semi aromatic polyamide (PA). has semi crystallization 态, has non crystallization 态, its 玻璃化 temperature degree in 255°F left right. non crystallization PPA main/primary used for requirements retardant property can combined; semi crystallization PPA resin main/primary used for injection molding processing, used for its it melt processing process. lower main/primary introduction rear 者?? semi crystallization 态PPA resin, especially remove outer. semi crystallization 态PPAS melting point is 590°F, transparent 矩形切 sheet/slice supply.
property can
PPA resin ratio type polyamide (PA) nylon 6, 6 and other more 结实坚 hard; for water separation degree more low; thermal properties more good; but also creep, fatigue and chemical resistant product property can good more. 例如: 含 45%玻璃 short fiber PPA resin, resistant strong/high degree 约276MPa, flexural modulus ultra- 13786MPa, heat deflection temperature (HDT) (HDT)549°F. make material filler grade PPA, resistant strong/high degree can to 117MPa. PPA resin property nylon 6, 6, however, already development reinforcement impact modified grade PPA resin, its 缺口悬臂梁式 impact strong/high degree high 达20英尺?磅/英寸.
has poly amine absorption water separation, increase function and dimensions 改变. nylon 6, 6, in 23°F lower, versus for wet degree is 100%时, can absorption 8.9% water separation, this make its 玻璃化 temperature degree 由6.5°C drop to 一20℃, dimensions increase 2.3%. in same conditions lower, PPA resin can absorption 约6% water separation, its 玻璃化 temperature degree Tg不会 low 于40℃, dimensions growth ultra- 1.0%.
positive front 面 提, use reinforcement PPA resin has very high HDT value, can resistant very high temperature degree short function, 例如: in 一 供炉 in or in versus and in outer 逆流团结 process in. PPA resin hot oxidation stability property make it can resistant long high temperature function, reinforced grade PPA, in 20 000 small inner, its use temperature degree can 达330°F.
in positive ring conditions lower, PPA resin usually for 脂肪烃, 芳香烃, chlorine 代烃, ester, ketone, alcohol and large more water solvent liquid performance excellent resistant solvent property. this category of resin can 经受极 strong/high acid and strong/high oxidation agent function. can solvent and 甲酚.
