摘要
本文介绍了ABS/PVC共混体系中添加α-SAN树脂,进行三元共混改性的研究,找出了能使共混物综合性能较佳的三元共混物的配方。实验证明,通过添加α-SAN树脂,可改进ABS/PVC共混物的性能,有利于该共混物进一步降低价格,扩大应用。此外,对该共混物中,最适宜于PVC改性用的ABS品种,也进行了选择性的探讨。
The modification of ABS/PVC blend by adding a-SAN resin was studied. A recipe for producing a mixture of three polymers with better physical and mechanical properties was found out. The experime- ntal results showed that the comprehensive property of the polyblend could be modified,the production cost was reduced and its application was expanded by adding a-SAN resin,The influences of various grades and amounts of ABS added were also studied.
