摘　　要：采用三釜连续聚合装置,开展连续本体ABS树脂研究。根据产品动力学参数,选定了3种过氧化物类引发剂,分析了产品在反应釜内的半衰期、分解曲线、残留物含量以及对本体ABS树脂性能的影响规律。从反应平稳控制、SAN的接枝效率、引发剂对基体树脂的强度、ABS冲击强度、耐热性的影响等方面对不同引发剂作出评价筛选。Mass process ABS was synthesized via a polymerization unit with 3 continuous reactors. According to the kinetic parameters,3 kinds of peroxide initiator was selected. With some theoretical and practical analysis,the impact on the properties of ABS caused by the half time period,decomposition curve and residue content was raised. From the points of stable reaction,SAN＇s grafting efficiency and the strength of ABS resin,the most suitable initiator for mass process ABS polymerization was put forward.
