摘要

聚乙烯醇缩丁醛(PVB)分子结构上含有大量羟基

可用于改进聚丙烯的非极性。本文采用不同结构的聚乙烯醇缩丁醛(B-98、B-76、B-72)与抗冲聚丙烯(ICPP)按5/95进行共混

并测试了共混物的相结构(SEM)、结晶过程(POM)、热性能(DSC)和力学性能。SEM测试结果表明

PVB和ICPP表现出一定的相容性

其中B-98相容性最好;DSC和POM测试结果表明

PVB对ICPP的结晶有抑制作用;力学测试结果表明

B-98改性ICPP后的综合力学性能效果优于B-76和B-72。B-98和聚丙烯较好的相容性主要和其较小的分子量有关。

Abstract

The molecule structure of polyvinyl butyral contains large part of OH group

which could be uesed to modify the nonpolartiy of polypropylene. Different structures of polyvinyl butyral (PVB: B-98

B-76 and B-72) were selected to modification impact polypropylene (ICPP) by melt blending method (PVB/ICPP: 5/95). The blend system of PVB/ICPP was studied by SEM

POM

DSC and mechanical properties test. The SEM result confirms that PVB shows party miscibility with ICPP

in which B-98 is the best. The results from POM and DSC show that PVB has a remarkable inhibitory effect on the crystallization rate of ICPP; The results from mechanical tests indicate that the comprehensive mechanical properties of B-98/ICPP are better than B-76/ICPP and B-72/ICPP. The better miscibility of PVB of B-86 with polypropylene is mainly due to its small molecular weight.
