工程塑料家族新成员——间同立构聚苯乙烯SPS

New Members of Engineering Plastics Family——Syndiotactic Polystyrene(SPS)

苯乙烯通过自由基聚合制成的通用塑料 PS已为人们所熟知,但国外应用单点位催化剂技术(Single-site catalyst technology)最新研制开发的间同立构聚苯乙烯却有望挤进工程塑料的行业,并即将推出其商业化产品。

The polystyrene as a large volume plastic prepared by radical polymerization is well known. But recently,the syndiotactic polystyrene based on the single-site catalyst technology is likely to be ranked among the engineering plastics,and its commercial products will go on the market abroad soon.
