摘要
通过乳液共聚合成了N-苯基马来酰亚胺/苯乙烯/丙烯腈三元共聚物,与聚氯乙烯(PVC)共混得到耐热PVC共混物,研究了共聚物组分含量对PVC共混物的力学性能、流变性的影响,用热分析法以及维卡软化点测定仪对共混物的耐热性进行了表征,同时考察了共混物的微观结构与形态。
Terpolymer of N - phenylmaleimide (PMl), acrylonitrile (AN) and styrene (St) were synthesized by emulsion polymerization. The thermal properties of PVC blended with the terpolymer were characterized by thermogravimetric analysis (TGA), torsion braid analysis (TBA) and Vicat softening point tester. The effects of the terpolymer content on the mechanical properties and rheological behaviour of the PVC blend were studied. The break surface and morphology of the blend was examined by means of scanning electron microscope.
