摘要: 研究了氯化聚氯乙烯(PVC-C) /聚氯乙烯(PVC)与抗冲改性剂MBS[聚丁二烯(PB)与甲基丙烯酸甲酯(MMA)及苯乙烯(St)按枝共聚物]的二儿共混物的物理力学性能和流变性能。结果表明:共混物的维卡软化点随PVC-C用量的增加而上升,在PVC-C/PVC=50 /50(质量比)处有一拐点。共棍物的拉伸强度、弯曲模量随PVC-C用量的增加而提高; 而冲山强度和断裂伸长率都随PVC-C用量增加而下降。共棍物中随PVC-C用量增加,塑化能力增强,平衡转矩上升。不同的加工助剂可降低共棍物熔体黏度,改善加工性能。

Abstract: Mechanical properties and rheological behavior of blends of polv(vinvl chloride)(PVC),chlorinatcd PVC(PVC-C ),and MBS arc investigated.The Vicat softening temperature of the blend increased with increasing content of PVC-C. The tensile strength and flexural modulus also increased with increasing content of PVC-C, while the impact strength and elongation at break decreased. In addition,PVC-C increased the equilibrium torque. The melt viscosity of the blends was reduced by the introduction of MBS.

Key words: chlorinated poly(vinyl chloride), poly(vinyl chloride), methylmethacrylate-butadicn-styrene copolymer, blend, blending modification, mechanical property, rhcological behavior
