碩士 === 淡江大學 === 化學工程學系 === 89 === Polyphenylene Sulfide PPS and Polyamide6、6 PA66 blend is Immiscible .It needs compatibilizer to improve its interfacial adhesion. The present study is planed to synthesize the compatibilizer copolymer in-situ in the interface during blending process and the nanoscale phase morphology of blends. The modification of PA6、6 is firstly activated by plasma reaction and followed by the grafting of GMA. The modified Polyamide mPA66 functionalized with epoxide groups is used to react furthermore with thio or tiolate group at the chain end of PPS. Such mutual reaction between PPS and mPA66 forms compatibilizer copolymer in-situ and stabilize the phases in the blend system. Detail study will cover the grafting efficiency, compatibility effect and the bi-continuous phase behavior of blends.
