用溶液聚合法合成了丙烯腈-三元乙丙橡胶-苯乙烯接枝共聚物(AES),研究了接枝聚合反应的影响因素,并进行了红外光谱表征.结果表明,三元乙丙橡胶(EPDM)已接枝上丙烯腈(AN)和苯乙烯(St)的共聚物(SAN)支链,即EPDM与AN及St发生了接枝共聚合反应.%Graft copolymerization of styrene and acrylonitrile onto EPDM with the solution-polymerization method was carried, the effect factors of eopolymerization were studied, characterization of the synthesized AES with infrared spectroscopy was made.It was showed that EPDM had grafted SAN branches that graft copolymerization of styrene and acrylonitrile onto EPDM had happened.
