| 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( 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] |
