A bulk polymerization monomer dehydroabietic acid-(2-acryloyloxy-ethoxy)-ethyl ester(DHADG-AC) was synthesized from dehydroabietic acid(DHA). The chemical structure of DHA-DG-AC was characterized by1~HNMR,(13)~CNMR, MS and FT-IR. The kinetics of the bulk polymerization of DHA-DG-AC was investigated by Differential Scanning Calorimeter(DSC).Two kinds of kinetic model(nth-order model and autocatalytic model) were used to investigate the polymerization process. The results showed that the experim e nt al DSC c u r ve s w e r e c o n si st e nt wi th t he computational data generated by the autocatalytic kinetic model, and the value of E_a was 95.73 k J·mol~(–1).
