四 types compatibilizer most new used as simple introduction:

compatibilizer classification

一.PC/ABS, PA/ ABS, PBT /ABS alloy compatibilizer

ABS resin already by used for engineering plastics alloy, 如PC/ABS, PA/ ABS, PBT /ABS  and other, this alloy can improve/increase ABS特定材 material defect. however, crystallization plastics 如PA, PBT不 and ABS versus 容. obtain industrial upper has use alloy, most excellent reaction type increase agent and its reaction control selection is very important.

DENKA electrical chemical industrial 株式会社 development IP compatibilizer can very good solution ABS and PA（ or PBT） versus defect. lower is IP structure 式:

IP separation 子式

我们 again 看看ABS structure 式:

ABS separation 子式

由 above types material structure 式看出: ABS and IP structure versus property relatively large; according to versus versus 容原则, IP and ABS, ASA, SAN versus property very good.

IP and PA, PC, PBT reaction mechanism

in can 团方面, IP tool has acid 酐基团, can and PA 氨基（ or PC, PBT 羟基）发生 chemical reaction. usually lower, grafting copolymer reaction in extrusion process in 进行.

案例 analysis:

以PA6 is 例: IP and PA6 extrusion reaction to IP grafting PA6 copolymer.

不含马 acid compatibilizer /PA6=35/65（ left ）, IP compatibilizer （含马 acid 酐）/PA6=35/65（ right ）, 源: DENKA electrical chemical industrial 株式会社

由 upper 图 示: has acid compatibilizer and PA6 dispersion ratio has acid compatibilizer good very more. another, IP resistant thermal properties good （Tg=196℃）, can improvement ABS, ASA resistant thermal properties.

二.PPO/PA alloy compatibilizer

PPO tool has other engineering plastics method ratio property can advantages, main/primary has: resistant solvent agent, flame retardant property can good, dimensions stability, specific gravity most light, water most small, electrical strong/high degree most high, high heat resistant and other. is, PPO melt flow property 差, thermoplastic processing difficult. 几乎不 can mono 独进行 extrusion and injection molding processing. market upper application PPO绝 large separation 都进行 modified, its in PPO/PA alloy is PPO modified main/primary methods 之一.

PPO/PA alloy comprehensive advantages, PPO/PA alloy force property can excellent, specific gravity light, hydrolysis resistant, high heat resistant, electrical property can excellent, dimensions stability, processing stability. is PPO and PA不 versus 容!

PPO grafting acid reaction increase chemical mechanism

PPO grafting acid can to PPO and PA increase 容: acid 酐基团 and PA amine reaction, formed large separation grafting material uniform dispersion to versus interface upper, to reaction increase function.

different MAH-g-PPO content for alloy dispersion 情况

如 upper table/sheet 示: 1）MAH-g-PPO can obvious improvement PPO/PA  alloy dispersion 情况; 2）当MAH-g-PPO content to 10% above, 继续添 add MAH-g-PPO improvement 效果不 obvious.

三.PC/ABS alloy

PC/ABS alloy is market upper currently application most more plastics alloy 之一. in PC/ABS in add masterbatch, if selection masterbatch defect, product easy silver streaks, and other defect:

low viscosity acid polyethylene wax masterbatch easy formed PC degradation

high viscosity ABS masterbatch 载体致 color powder difficult dispersion

佳 easy launch masterbatch 载体: EMI-100 . EMI-100 dispersion mechanism is: EMI-100 through lubricating, function distribution in color powder surface, decrease small color powder micro between function force; from 而避免 color powder distribution defect.

EMI-100浸 lubricating property, high flow property, versus property ensure PC/ABS masterbatch excellent dispersion property and 无迁移析出 phenomenon.

EMI-100 dispersion mechanism

table/sheet 1: PE wax, SAN, EMI-100 degree L value

注: PE wax, SAN, EMI-100载体炭黑 masterbatch add amount separation is 1%, 1.7%, 1.3%

佳 easy launch 40%炭黑 concentrated degree EMI-100载体 masterbatch in same 0.5%炭黑 concentrated degree 时 L value obvious low 于普通 SAN载体 masterbatch, and PE wax versus 当.

from left right separation is: EMI-100, POE（不含EBS）, SAN, PE腊, POE（EBS）

upper can 看出: remove EMI-100, other masterbatch need has silver streaks, need 不出现麻点.

四.基于 versus technology has machine modified silicon oxygen 烷

poly 二甲基 silicon oxygen 烷俗称 silicon ketone, 简称PDMS, is types hydrophobic water type has machine silicon material material. silicon ketone color 无味, used as lubricated 油, anti 振油, insulation 油, defoamer, demolding agent and other.

PDMS separation 子式

由PDMS separation 子式看出: material 质由无 machine and has machine 侧链组 formed; has property 甲基官 can 团包覆 in has property silicon oxygen 主链周围, this make PDMS separation function force very small.

oxygen silicon 键（ left ） and carbon carbon 键（ right ）

and carbon carbon versus ratio, silicon oxygen 键 键 long more large, more large, can amount more low; silicon oxygen tool has good flow property and relatively low 玻璃化 temperature degree.

table/sheet 2: Si键 and C键键 can comparison

PDMS主链Si-O键 can amount high, this make it tool has resistant thermal properties.

PDMS will has machine and machine 主链结 combined 起, also tool has above excellent property can; widely used in lubricated 油, anti 振油, insulation 油, defoamer, demolding agent and other.

however, PDMS也 has 不足之处: and resin versus property 差, specific performance is in processing process in PDMS distribution 不均, in application process in has 迁移, viscous and printing defect and other issues.

Evonik development has machine modified silicon oxygen 烷（OSM）TEGOMER®, separation structure 示意图如 lower:

has machine modified silicon oxygen 烷（OSM） separation structure 示意图

PDSM主链 ensure high surface active property, has machine can ensure and polymer/macromolecule resin has good versus property. its in has machine 侧链R包括: 烷基, polyester, acrylic ester, ring oxygen resin, 羟烷基, 氨基烷基.

has machine modified silicon oxygen 烷（OSM） 锚 solid 效应

has machine can to below/following 效果:

1）OMS and polymer ensure strong/high large solid 效果;

2） can 避免迁移 to parts and mold surface;

3）避免 silicon poly formed 斑点, 导致严 heavy defect.
