    Abstract: 本論文主要是研究在PPS/PA12摻合系統中, 加入反應性單體 MAH 及Styrene, 使得這兩種單體能藉由原位(In-situ)反應的方式, 在相界面間原位生成(In-situ formation)所需要的相容劑。並藉由熱溶洗出連續相的方法, 收集分散相, 以FTIR做相界面共聚物含量的定量分析。而動態機械分析(DMA)及微觀相型態(SEM)等測試, 則被用來探討相界面共聚物含量對摻合系統所造成的影響。研究結果發現:在PPS/PA12(30/70)摻合系統中, 加入MAH及Styrene單體, 可以大幅提高相界面含量, 而MAH與Styrene的最佳比例為 2:2 phr。動態機械分析顯示, 相界面共聚物含量增加, 會使得PPS與PA12的玻璃轉移溫度更相互靠近。而在微觀相形態的觀察, 則發現加入單體後, 相界面有變化顯示有相容性共聚物的生成。
    The polyblends of PPS and PA12 were studied. It is observed that addition of small molecules with multi- functionality, maleic anhydride (MAH) and styrene, during blending of PPS and PA12 increases the compatibilization between these two polymers. This is due to the fact that MAH and styrene can react with PPS and PA12 to form in- situ, block copolymers PPS-b-PA12 at polymer interface, which is confirmed by FTIR spectrometry. The evidence of improving compatibility due to reactive blending is revealed by analysis of dynamic mechanical behavior and morphology.
