摘要: 用透射电子显微镜和X射线衍射等方法研究了等规立构聚丙烯(iPP)和无规立构聚丙烯(aPP)共混物溶液浇铸膜的形态结构,结果表明,aPP的加入对iPP的形态结构有很大的影响。

Abstract: Morphologies of solution-cast films of iPP/aPPblends have been studied by means of electron microscopy and X-ray scattering techniques. Microscopic observation showed that solution-cast film of iPPconsists of two kinds of structural regions, cross-hatched and lath liked structures. The addition of small amount of aPP (≤300%) into iPPdid not change iPP' s characteristic crystallization behavior. It is noticed that when the content of aPPin its blend was over 80%, iPPformed a very loosely woven-like network composed of very long lameilae with wide-angle lamellar branchings. The X-ray data showed that aPPdid not cocrystallize with iPP.
