摘要
介绍了间规聚苯乙烯 (sPS)的结构、特性和各种化学改性方法 ,包括在sPS侧链苯环上引入磺酸基、卤素等功能基因 ,在sPS分子链末端引入马来酸酐、丙烯酸酯等极性基团 ,与氢化丁二烯-苯乙烯热塑性弹性体 (SEBS)形成接枝共聚物 ,及其与各类烯烃单体的共聚 ,对进一步拓宽sPS的应用领域具有重要意义。
Syndiotactic polystyrene(sPS)is a newly crystal engineer plastics.Compared with atactic polystyrene,it has perfect properties, such as high thermal resistance temperature,high crystallization velocity and chemical resistance.So the research on sPS has carried out recently.In this paper,structure, properties and chemical modification methods were discussed,which including the introduction of functional group(sulfonation,halogenation,maleic anhydridition) to molecular chain of sPS,copolymerization of sPS with other olefin monomers.
