PPS/PA12的聚摻合,PA12分散相粒子的粒徑大小,不會因反應性單體(GMA、MAH)的加入而有明顯的變化,但是,其微觀相形態與熱行為卻有極大的差異。GMA與MAH具有雙官能基,藉此與聚摻合物中不同相的高分子以原位化學反應在界面形成PPS-PA12段式共聚合物充作相容劑,使PPS的結晶態有部分轉移成無定形態,有利於PPS的增韌效果。GMA會使PA12產生交聯反應,在PPS連續相中形成PA12第二分散相。 This report presents a study of the relationship between morphology and chemical reaction of PPS/PAl2 reactive blends. Adding difunctional groups monomers (GMA, MAH) in PPS/PAl2 blends increases the reactivity of blends and produces more PPS-PAl2 block copolymers as compatibilizer. GMA monomers make PAl2 crosslink and this results in forming an additional second dispersed phase in PPS matrix. These evidences can be observed by the analyses of SEM and DSC.
