以苯乙烯-马来酸酐无规共聚物(SMA)为有机组分，以正硅酸乙酯(TEOS)为无机组分，利用sol-gel方法制得纳米杂化材料.以此为载体合成了载体化钛系催化剂，进行了苯乙烯聚合的研究.聚合结果表明在50℃左右聚苯乙烯的间规度达到最大；随着反应温度的提高，分子量出现了下降现象，但反应活性提高，在70℃时，可达最高1.49×106g/(mol·h)；并且分子量分布与文献结果相比也较宽.
The use of organic/inorganic hybrid materialspoly(styrene-co-maleic anhydride)/SiO2 as the support for titanium catalysts in styrene polymerization was studied. Results indicated that at 70 ℃ the activity of the inorganic/organic hybrid supported catalysts would reached a maximum; 1.49×106 g/(mol*h). With increase in reaction temperature, the molecular weight of polymer decreased, and the polydispersity was much wider. DSC and FTIR measurements showed that the product was syndiotatic polystyrene.
