Ring-opening polymerization of isopropylglycidyl ether (IPGE) with new catalysts of Ti, Sn, Al-alkoxides and comparison of its reactivity

Abstract

The polymerization reactions of isopropylglycidyl ether (IPGE) were carried out by various catalysts potassium hydroxide, potassium tert-butoxide, tetrafluorophthalate aluminum sec-butoxide, tetrafluorophthalate tin tert-butoxide, and tetrafluorophthalate-titanium isopropoxide complexes. Tetrafluorophthalate-aluminum, tin, and titanium have been prepared from aluminum sec-butoxide, tin tert-butoxide, and titanium isopropoxide in alcohol and tetrafluorophthalic acid. Poly-IPGE and catalysts were characterized by ¹H, ¹³C NMR, FTIR spectroscopy, elemental analysis, and gel permeation chromatography. IPGE is less reactive toward OH^- nucleophiles than 3-glycidyloxypropyltrimethoxysilane and propylene oxide.
