The reactions of unsaturated chloride polyether polyol with trimethyl phosphite have been studied by FTIR, which was prepared by copolymerization of ethanediol, allyl glycidyl ether and epoxychloropropane. The experimental results showed that the reaction included ester-exchange reaction, ester-exchange polymerization and
