摘要/Abstract

摘要： 采用固相法制备马来酸酐接枝氯化聚氯乙烯(CPVC-g-MAH)，得到了接枝率达2.91 %的CPVC-g-MAH，并对其进行了性能测试，探讨了聚氯乙烯(PVC)/CPVC-g-MAH共混物的冲击性能和加工性能，与PVC/氯化聚氯乙烯(CPVC)共混物进行对比以观察改性效果。结果表明，CPVC-g-MAH的热性能较CPVC有较大提高；PVC/CPVC-g-MAH共混物的冲击性能比PVC/CPVC共混物有所提高，而平衡转矩有所降低，说明CPVC-g-MAH相比于CPVC对PVC共混物加工性能改善效果更加明显。

Abstract: Chlorinated poly(vinyl chloride) (CPVC) was grafted with maleic anhydride(MAH) via solid-phase grafting copolymerization.Grafting degree (GD) of copolymer CPVC-g-MAH was 2.91 %. The thermal stability, impact strength, and processability of the PVC/CPVC-g-MAH blends were evaluated, and compared with those of PVC/CPVC blend. It showed that CPVC-g-MAH exhibited a higher thermal stability than CPVC. The impact strength of PVC/CPVC-g-MAH blends was higher than that of PVC/CPVC blends. The equilibrium torque of PVC/CPVC-g-MAH blends was lower than that of PVC/CPVC blends, which indicated CPVC-g-MAH provided processing.

Key words: CPVC, MAH-g-CPVC, MAH-g-CPVC/PVC blends, structure and properties
