  PC toughening agent is PC and PC alloy （PC/ABS,PC/PET,PC/PET,PC/PS and other ） toughened 进行阐述, PC and PC alloy material versus toughening agent has multiple selection, can to toughened function, most commonly used ABS grafting material, HDPE(LLDPE) grafting material, EPDM grafting MA or GMA, SBS(SEBS) grafting, ABS high powder, PS grafting, housing/shell structure MBS resin, silicon resin modified 包袱MBS resin, EMA series, EBA series and other, in certain scope/range inner is can to toughening agent function, can is PC材 material in different field/area use, requirements parameters versus different. has use field/area can effect/influence PC heat resistant property, has use field/area requirements low temperature （-25~ -40OC） impact property can good (this type of can is resistant toughening agent), has field/area requirements tensile strength need very good, has application areas requirements weather resistance can excellent, has application areas requirements super tough 效果.

    currently development toughening agent main/primary day is is improvement hard polyvinyl chloride (PVC) property. world upper hard polyvinyl chloride (PVC) use amount growth and toughening agent development, processing modifier day development has 密切 关系. USA is 例, 1965 year polyvinyl chloride (PVC) in hard 质 占10%, 1970 year rise is 20%, to 1975 year 占40%, 1980 year ultra- 50%, expected to 2000 year will 达75%. add increase agent polyvinyl chloride (PVC) in 40℃ below/following 时就呈脆 property, but also in add relatively less increase agent 时, not only can toughened 反而促 make its property, this is 谓 反 increase 塑效应, therefore add toughening agent hard polyvinyl chloride (PVC) has very large use value.

    toughened polyvinyl chloride (PVC) method is through copolymer let polyvinyl chloride (PVC) inner increase 塑, method not only but also 效果不佳. 不久发现添 add certain elastomer can reduce polyvinyl chloride (PVC) temperature degree, most commonly used additives is 二烯烃 or acrylic polymer, especially is butadiene polymer due to its 玻璃化 temperature degree low tool has most good toughened property, 例如ABS, MBS is polyvinyl chloride (PVC) most commonly used main/primary toughening agent. PC toughening agent 发现 in addition, 0PE and EVAJ, type 橡胶, acrylic ester polymer and surface use hard acid coating carbon acid and other is polyvinyl chloride (PVC) has toughening agent.
