新型硫掺杂聚苯乙烯的制备与表征

本工作研究一类新型硫掺杂聚苯乙烯的制备方法。以对氯甲基苯乙烯和苯乙烯为原料，在偶氮二异丁腈（AIBN）引发下，制备对氯甲基苯乙烯的均聚物和与不同比例苯乙烯共聚的共聚物，此氯甲基化聚苯乙烯与乙基磺原酸钾反应，即可以高产率制备不同硫掺杂聚苯乙烯。该方法操作简单，条件温和。聚合物结构经红外光谱、核磁共振氢谱表征，聚合物相对分子质量经凝胶渗透色谱分析检测。同时还对硫掺杂聚合物的成膜性能进行了初步研究，结果表明，该聚合物成膜性能良好。

Preparation and Characterization of New Type Sulfur Doped Polystyrene

The preparation method of a new type sulfur doped polystyrene was studied. Under the initiator of AIBN, homopolymer and copolymer with styrene were synthesized from p-chloromethyl styrene. The chloromethyl polystyrene can react with potassium ethyl xanthate to produce sulfur doped polystyrene. This method is simple and the condition of reaction is mild. The structures of the polymer were characterized by means of IR and 1H NMR. The relative molecular mass of polymer was detected by gel permeation chromatogram (GPC) and the doped amount of sulfur atom was analyzed by element analysis. At the same time, the performance of film formation was also studied. The initial results show that the polymers have a good film characteristic.The preparation method of a new type sulfur doped polystyrene was studied.
