| 摘 要： | 利用聚乙烯吡咯烷酮共聚对聚苯乙烯微球的表面改性进行碘催化剂的固定化,制备粒径均一、可循环使用的催化剂微粒.红外光谱研究表明,聚乙烯吡咯烷酮和苯乙烯的共聚,进入聚苯乙烯聚合链中,碘的负载主要通过与聚合链中吡咯烷酮基团的配位进行,由此对吡咯烷酮相关的特征振动产生较大影响.

| Abstract: | Surface property of polystyrene particles was modified with copolymerized polyvinylpyrrolidone,and a uniform and recyclable iodine catalyst particles were prepared by loading iodine onto the copolymer particles.IR spectral characterization indicates that the polyvinylpyrrolidone was incorporated into the polymer chain of the polystyrene.The Loading of iodine molecules was achieved by the interaction with pyrrolidone residues,which leads to a significant spectral change of the pyrrolidone group. |
