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,还适合于具有严重交替倾向的共聚物.

Abstract: The glass transition temperature( Tg) 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 Tg were investigated. An equation in term of copolymer composition and sequence distribution was presented to predict Tg of copolymer. The equation can be used to describe not only the random copolymer, but also the copolymer with the alternating tendency.

Key words: Vinyl monomer, N-Substituted maleimide, Glass transition temperature
