摘要
PP和PS是不相容的聚合物 ,直接机械共混的产物性能较差 ,通过添加相容剂 ,如嵌段共聚物或接枝共聚物能提高共混物性能。在线增容技术已用于PP、PS反应性增容 ,生产高性能的合金。
Owing to the incompatibility of PP and PP, their blends with inferior properties by direct mechanical melt mixing, strength enhancement of the blends can be achieved by adding the compatibilizer, such as a block copolymer or grafted polymer. In situ reactive compatibilization techniques have been used for both polystyrene and polypropylene, and also production alloys with superior properties.
