ABS树脂合成路线、结构、性能和新品种

Polymerization Processes, Structure, Properties and New Varieties Grades of ABS Resins

本文根据50篇参考文献和专利,对ABS树脂(丙烯腈-丁二烯-苯乙烯三元共聚物)的合成路线、结构性能和新品种作了综述.在简介了橡胶增韧聚苯乙烯系列,特别是ABS以后,首先描述了乳液、本体-悬浮、连续本体3种制备ABS的聚合方法,并作了评价.然后讨论了3组份的比例、橡胶颗粒大小、接枝率等对ABS树脂抗冲、耐热、流动、透明、耐候等性能的影响.最后介绍高抗冲型、透明、耐热、阻燃、电镀型等ABS新品种和其合金,以及有关生产关键和应用领域.

In this paper, The polymerization processes, structure, properties and new grades of ABS resins were reviewed from 50 references. After a brief a introduction to rubbertoughened polstyrene series, especially ABS, the emulsion, bulk—suspension and continueous bulk polymerization processes for manufacturing ABS were described and evaluated firstly. Thereafter, the effects of the ratios of three components, the particle size of rubber and graft degree on high - impact, heat—resistant, transpant, frame—resistant and electroplating properties were discussed. Finally, various types and grades of ABS resins, its manufacturing key factors and applications were introduced.
