摘要
采用一种新型超细丁苯粉末橡胶作为增韧剂,提高聚丙烯(PP)韧性,考察了粉末橡胶的含量、相容剂的种类和用量对PP性能的影响。利用TEM和SEM考察了改性PP中粉末橡胶的分散状态,同时采用DSC研究了粉末橡胶对PP结晶性能的影响。
A new type of powdered rubber of ultrafine styrene butadiene is used for preparation of toughened polypropylene. The influences of contents of powdered rubber and compatilizer on the properties of PP are investigated. Dispersion of powdered rubber in modified PP is studied by TEM and SEM. Meantime, the effect of powdered rubber on crystallization of PP is studied by DSC.
