THE EFFECT OF MOLECULAR WEIGHT AND ITS DISTRIBUTION ON CRYSTALLINE MORPHOLOGY OF PP MATERIALS
Author(s): 
Pages: 166-168,173
Year: Issue:  5
Journal: POLYMER MATERIALS SCIENCE & ENGINEERING

Keyword:  聚丙烯分子量分子量分布结晶形态;
Abstract: 研究了不同分子量及其分布下聚丙烯材料结晶形态的变化规律,结果表明,用分子量分布宽度MWD这一参量来描述不同分子量及其分布下材料结晶形态的变化规律更为恰当.分子量的多分散性意味着高、低分子量组分之间存在明显的相互作用,决定了聚丙烯材料最终的结晶形态.
