中文摘要：
對位性聚苯乙烯是一種高結晶性的高分子材料，具有高熔點（270℃）、結晶速度快、高耐熱溫度，耐化學性…等優異的物理性質。但因對位性聚苯乙烯之特殊結晶型態及高對位性之分子排列結構與不具備極性官能基，使得對位性聚苯乙烯與其它高分子摻混相容性不佳。
本論文中，包含 (１)使用有機茂金屬觸媒(metallocene)／鋁氧烷(methyl aluminoxane)與TIBA ( triisobutylaluminum)／氫氣系統合成對位性(苯乙烯/4-甲基苯乙烯)共聚合物。(２)以對位性(苯乙烯/4-甲基苯乙烯)共聚合物作為基材，加入強鹼 (nBuLi) 將4-甲基苯乙烯中的甲基位置予以金屬化，並加入苯乙烯單體進行接枝聚合反應合成出所需之相容劑sPS-graft-aPS。(３)探討上述相容劑對於sPS/aPS及sPS/ SEBS合膠之效益。
從NMR、DSC、DMA圖譜以及SEM的佐證，證實有機茂金屬觸媒系統與丁基鋁的使用以及共聚單体的加入，確實能夠合成接枝型之高分子聚合物並能導入合膠中增加其相容性。

stract:
Syndiotactic polystyrene (sPS) a high crystalline engineering plastic has been the focus for research in both academic and industry because of its elevated physical properties including high melting temperature (270℃),low dielectric constant, high moisture and chemical resistance and high heat resistance. However, the low compatibility of sPS with other material and the fragility in sPS limit its commercial applications. In order to circumvent these deficiencies in sPS, a syndiotactic polystyrene-graft- atactic polystyrene (sPS-graft-aPS) was prepared by undergo the coordination polymerization of styrene/paramethystyrene by metallocene catalyst followed by anionic grafting copolymerization of styrene.
The resulting copolymer were fully characterized by nuclear magnetic resonance ( NMR) and differential scanning calorimetry (DSC) analyses to indicate that the resulting copolymer contains both syndiotactic and atactic polystyrene conformations (sPS-grafted-aPS) Consequently, utilizations of this copolymer to improve the compatibity between sPS /aPS and sPS /SEBS were studied in this work.
