摘 要: | 用Mayo-Lewis方程式预测了悬浮共聚反应过程中偏氯乙烯/甲基丙烯酸甲酯(VDC/MMA)和偏氯乙烯/氯乙炮(VDC/VC)共聚物组成与转化率的关系。结果表明,在高转化率下,VDC/MMA共聚过程中产生了VDC均聚物,而VDC/VC共聚过程中产生了VC均聚物,在这两个共聚体系中加入适当的少量第三单体,可使产生均聚物的这一不利情况得到改善。

Prediction and discussion of vinylidene chloride copolymer composition |
| |
Abstract: | Vinylidene chloride/methyl methacrylate(VDC/MMA) and VDC/viny1 chloride(VC) copolymer composition were predicted by Mayo-Lewis equation. It was found that under high conversion, VDC homopolymer was formed in VDC/MMA compolymerization, whereas VC homopolymer in VDC/VC compolymerization. The disadvantaged case can be improved by the addition of the suitable third monomer in the copolymerization system. |
