α-Chlormethyl α methyl β propiolactone(CMMPL)was synthesized by dehydrochlorination of dichloromethyl propionic acid(DCMPA)in the presence of DOH.The ring opening polymerization of CMMPL was successfully carried out by using Sn(Oct)2
Ti(OBu)4
Al(i OPr)4 and Al(Et)3 as initeators in bulk or solution.Powder X ray diffraction and DSC measurement showed that P(CMMPL) was a kind of high crystalline polymer. Both the polymerization conversion and the properties of the polymer were affected by the monomer concentration and the polymerization time.
