Abstract

Ring-Opening copolymerization of epichlrohydrin (ECH) with maleic anhydride (MAn) was catalyzed by yttriun phosphenate in combination with triisobutylaluminum for the first time to give almost alternate copolymer, functional polyester. The yield and composition of the copolymer were affected by the reaction conditons, especially the initial monomer charge ratio. The overall activation energy of the copolymerization was estimated to be 19.Okeal/mol. Evidence for the structure of ECH-MAn copolymer prepared was obtained by IR adn1H-NMR.
