Study on the Polymerization with Organic/Inorganic Hybrid-Supported Titanium Catalysts Ⅱ.Styrene Polymerizaton
摘要
Abstract
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.关键词
