Synthesis and bulk polymerization kinetics of monomer dehydroabietic acid-(2-acryloyloxy-ethoxy)-ethyl ester

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 by1HNMR,（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 Ea was 95.73 k J·mol–1.
