采用氯化原位接枝法制备CPVC-g-HEA与CPE-g-MAH,高温共混后得到CPVC-g-HEA/CPE-g-MAH共混物。研究发现:与CPVC/CPE共混物比较,CPVC-g-HEA/PE-g-MAH共混物由于大分子间发生了反应,产生了新的化学键,使性能有较大的变化。初步探讨了这一新聚合物体系的共混过程;以反应共混物的应力-应变曲线、维卡软化温度等表征了材料的物理力学性能;以扫描电镜(SEM)考察了共混体系的形态结构。 CPVC-g-HEA and CPE-g-MAH were prepared by in-situ grafting of chloride. CPVC-g-HEA / CPE-g-MAH blends were obtained after blending at high temperature. The results showed that CPVC-g-HEA / PE-g-MAH blends reacted with macromolecules to produce new chemical bonds, which resulted in great changes in properties compared with CPVC / CPE blends. The blending process of this new polymer system was discussed preliminarily. The stress-strain curve and Vicat softening temperature of the blends were used to characterize the physical and mechanical properties of the blends. The scanning electron microscopy (SEM) Morphology.
