摘　　要：不可逆加成-断裂链转移剂合成容易,产率高,无恶臭,广泛用于分子量的调节。本文通过α-甲基苯乙烯溴代后与硫醇类链转移剂合成十二烷基二苯基硫烯丙基硫型不可逆加成链转移剂,用于调节ABS分子量,研究了分子量调节剂对丙烯腈-丁二烯-苯乙烯树脂(ABS)分子量及其它性能的影响,通过红外光谱仪、核磁共振氢谱仪对产物的结构进行表征,结果表明已成功地合成出目标产物。The irreversible addition-fragmentation chain transfer agent is easy to synthesize,has high yield,has no malodor,and is widely used for molecular weight adjustment.In this paper,a non-reversible addition chain transfer agent of lauryl diphenyl thioallyl sulfotype was synthesized by bromination ofα-methylstyrene with a thiol chain transfer agent to adjust the molecular weight of ABS.The structure of the acrylonitrile-butadiene-styrene resin(ABS)was characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy.The results showed that the target product was successfully synthesized.
