toughening agent can separation is type toughening agent and thermoplastic property elastomer type toughening agent:
（1）橡胶 type toughening agent type toughening agent product types main/primary has liquid poly 硫橡胶, liquid acrylic ester 橡胶, liquid poly butadiene 橡胶, 丁腈橡胶, 乙丙橡胶 and 丁苯橡胶 and other.
（2） thermoplastic property elastomer thermoplastic property elastomer is type in normal temperature lower 显示橡胶 elastic property, in high temperature lower also can molding combined formed material. therefore, this category of polymer has and thermoplastic property plastics features, it can as is composite/compounding material toughening agent, also can as is composite/compounding material 基体材 material. this category of material main/primary polyurethane ester type, styrene type, polyolefin type, polyester type, 间规1,2- poly butadiene type and polyamide (PA) type and other product, currently as is composite/compounding material toughening agent use relatively more is styrene type and polyolefin type.
its it toughening agent suitable for composite/compounding material its it toughening agent also has low separation polyamide (PA) and low separation non active property toughening agent, 如苯二甲 acid ester type. for/regarding non active property toughening agent can is increase agent, it and resin solid reaction.
（一） 橡胶 type
1. 乙丙橡胶（EPR）
乙丙橡胶 is ethylene, propylene is main/primary mono raw materials, using/adopting has machine metal catalytic agent, in solvent liquid lower copolymer formed 无定形橡胶. according to is add non 共轭二烯 type as is saturated and mono 体, 乙丙橡胶 also can separation is binary copolymer and terpolymer large type. usually propylene content is 40%-60% left right, mono content is 2%-5%, molecular weight 25万 above, distribution relatively wide. 乙丙橡胶 in due to propylene 以无定 type 排列, bad polyethylene (PE) crystallization, formed is 不规整 copolymer non crystallization 橡胶, meanwhile also polyethylene (PE) certain features. binary 乙丙橡胶 in separation upper has di 键, formed is saturated and 状态, 因而构 formed 丁该橡胶 独 features can. ternary 乙丙橡胶 although a small amount of saturated and 基因但 di 键处于侧链 upper, therefore basic property can more large 差异. 乙丙橡胶 basic upper is types saturated and polymer/macromolecule combined material, separation inner has property 取代基, comparison 柔顺. it resistant oxygen property, weather resistance, resistant aging property in general purpose in is most good, its electrical insulation property, chemical resistant product property and impact resistant property relatively good.
乙丙橡胶 is commonly used toughening agent 之一, in polyethylene (PE) in use amount high 达40%.
2. poly butadiene 橡胶（BB）
poly butadiene is butadiene is mono 体, using/adopting different catalytic agent and polymerization methods made types general purpose type combined formed 橡胶. using/adopting different system and polymerization methods made poly butadiene in structure and property can upper has different. poly butadiene 橡胶 玻璃化 temperature degree is -105℃, molecular weight distribution relatively narrow, comparison less, ash content content 0.10%-0.15%, cold property small.
3. 丁基橡胶
丁基橡胶 is 以异丁烯 and a small amount of 异戊二烯 is mono 体, using/adopting chlorine aluminum or fluorine as catalytic agent, in low temperature lower （-95℃） polymer copolymer. this is types white viscous elastic property solid 体, has cold property, specific gravity is 0.92g/ml.
丁基橡胶 heat resistant property, weather resistance very good, resistant solvent agent property, electrical insulation property can relatively good.
4. 丁腈橡胶
general purpose type 丁腈橡胶 is butadiene 1,3 and acrylonitrile copolymer formed, its oil resistant property acrylonitrile content increase improve/increase. 丁腈橡胶 low temperature property can relatively 差 玻璃化 temperature degree and acrylonitrile content has 关, content more 则玻璃化 temperature degree high. 丁腈橡胶 heat resistant property relatively good, can in 120℃ lower use, electrical insulation property generally.
5. 丁苯橡胶
丁苯橡胶 is 以丁二烃 and styrene is mono 体, in emulsion or solvent concentrated in use catalytic agent catalytic copolymer formed polymer/macromolecule elastomer, specific gravity 0.98g/ml, 玻璃化 temperature degree -52℃. generally poly 丁苯橡胶 in has 23.5% styrene, polymer micro structure polymerization conditions 变化也 has very large 差异.
