Crystallization Behavior of High Melt Strength Polypropylene/Block Polypropylene Blends
摘要
Abstract
High melt strength/block polypropylene(HMSPP/PP-B) blends were prepared by a twin-screw extruder. The non-isothermal crystallization behavior of the blends was studied using differential scanning calorimetry by various cooling rates and was analyzed with Jezionry method. The morphology of spherulites of blends were observed by POM. It was found that the melt and crystallization temperature of blends increased with the increasing of PP-B. Besides, PP-B could change the crystallization process of blends leading to smaller spherulites size and more spherulites amount.关键词
