摘　　要：用 DSC和 TBA两种方法测定了苯乙烯 -丙烯腈 - N-苯基马来酰亚胺乳液共聚物的玻璃化温度 Tg,研究了共聚物的流变性能 ,测定了共聚物的熔体流动指数 n,发现共聚物的熔体流动指数越大 ,两种方法测定的共聚物的 TgThe glass transition temperature of styrene acrylonitrile N phenyl maleimide emulsion copolymer was determined by DSC and TBA method. The terpolymer′s rheological property and flow index n were studied. The result shows that T g increases with the increasing PMI content while T gTBA and T gDSC of terpolymers showed different tends. The rheological studies show that T gTBA - T gDSC increases with the increasing of the terpolymer′s flow index.
