基体分子量对PP/POE共混体系脆——韧转变的影响
Effects of Matrix molecular weight on brittle-tough transition of PP/POE blends
摘要
Abstract
In this article, the relationship between matrix molecular weight and brittle-tough transition of PP/POE blends was studied. It is shown that brittle-tough transition temperature increase with increasing interparticle distance of matrix in the same matrix molecular weight. The critical interparticle distance of matrix of PP/POE blends decrease with increasing matrix molecular weight. Brittle-tough transition of PP/POE blends was obtained in small interparticle distance of matrix of low temperature or big interparticle distance of matrix of high temperature.关键词
