摘　　要：采用不同聚合度PVC作为基体,研究了高聚合度PVC对制品的玻璃化转变温度、力学性能、加工性能的影响。结果表明:高聚合度PVC能够有效地提高断裂伸长率、拉伸强度、玻璃化转变温度、增塑剂吸收能力、加工温度,在耐热等级高的电线电缆中有着广泛的应用。The influence of high-polymerization degree PVC used as matrix on the mechanical properties, glass transition temperature and processing performance of products was studied. The results showed that high-polymerization degree PVC could effectively improve the properties of products, such as elongation at break, tensile strength, glass transition temperature, plasticizer absorption ability, and processing temperature, and it would be widely used in wires and cables of high heat resistance grade.
