[Studies on the reactions of unsaturated chloride polyether polyol with trimethyl phosphite by FTIR].
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 Arbuzov rearrangement. The process conditions such as catalyst, mass rate and reaction time were determined through the experiments. The analytic results indicated that the reaction temperature was the key controlling the process and the reaction products are suitable for reactive multifunctional flame retarders.
