Novel Initiators Having Acetylene Group for Polymerization of 2-Oxazolines

Abstract

Abstract Propagylic halide type compounds such as propagyl bromide, 1,4-dibromo-2-butyne, and 1,6-dibromo-2,4-hexadiyne, were used for the polymerization of 2-oxazolines. The polymerization initiated by these initiators gave polymers with narrow molecular weight distribution. From kinetic study, the polymerization using these initiators is found to be a relatively fast initiation system.
