? 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 concentreation and the polymerization time.
