Abstract
The polymerization reactions of styrene oxide (SO) at different temperatures for different time intervals were performed by four different tin catalysts, tin(IV) perfluorooctanoate (PFO-Sn), tin(IV) methacrylate (MAc-Sn), tin(II) chloride (SnCl2), and SnCl2/hexamethyldisilazane. Tin(IV) perfluorooctanoate and methacrylate compounds have been prepared from perfluorooctanoic acid, methacrylic acid, and tin tert-butoxide in tert-butanol. The Sn-PFO and Sn-MAc compounds were characterized by 1H, 13C NMR, FTIR, and elemental analysis. These four compounds were tested as catalysts in polymerization of SO and were effective. Polystyrene oxide (PSO) was characterized by 1H, 13C NMR, and gel permeation chromatography. High molecular weight of PSO (~138,000 Da) was recorded for the first time by this study.
