聚己内酯（ＰＣＬ）和丙烯腈－苯乙烯无规共聚物（ＳＡＮ）的共混物的相容性和形态曾被广泛研究［１～４］．ＰＣＬ的结晶形成球晶结构，其和ＳＡＮ共混，在熔体中结晶时不但可观察到Ｍａｌ－ｔｅｓｅ十字消光，而且存在非常明显的明暗交替的周期性环带状结构，称之为“环...
The compatibility and morphology of blends of polycaprolactone (PCL) and acrylonitrile-styrene random copolymer (SAN) have been extensively studied [1-4]. Crystallization of PCL forms a spherulitic structure that is blended with SAN. Not only Mal-tese cross-quenching is observed during crystallization in the melt, but also a very pronounced periodic structure of alternating light and dark bands called "ring ...
