最近,聚合物之间的附生结晶引起人们的极大兴趣和关注。附生结晶是一种结晶物质在另一种结晶物质上的取向生长,二者之间有特殊的作用。这种附生作用对结晶聚合物共混体系的形态结构和性能有极为重要的影响。本工作以电子显微镜方法研究熔体拉伸直接导致等规聚丙烯(iPP)和高密度聚乙烯(HDPE)共混物附生结晶。
Recently, epiphytic crystallization between polymers has drawn great interest and attention. Epiphytic crystallization is a crystalline material in another crystalline material orientation growth, the two have a special role. This epiphytic effect has a very important influence on the morphology and properties of the crystalline polymer blend system. In this work, the study of melt tension by electron microscopy directly led to the epiphyte crystallization of iPP and HDPE blends.
