摘　　要：用差示扫描量热仪对乙烯基单体 /N 取代马来酰亚胺共聚物的玻璃化温度 (Tg)进行测定 .研究了共聚物组成、序列结构、乙烯基单体和N 取代马来酰亚胺种类对共聚物Tg 的影响 .提出了含共聚物组成和序列结构的Tg 预测方程 ,该方程不仅适合于无规共聚物 。The glass transition temperature( T g) of vinyls/ N substituted maleimides copolymers was determined by differential scanning calorimeter(DSC). The effects of copolymer composition and sequence distribution, types of vinyls and N substituted maleimide on T g were investigated. An equation in term of copolymer composition and sequence distribution was presented to predict T g of copolymer. The equation can be used to describe not only the random copolymer, but also the copolymer with the alternating tendency. [WT5HZ]
