Abstract: N-dehydroabietic acrylamide, a polymerization monomer, was synthesized via amidation reaction of acryloyl chloride and dehydroabietylamine which was synthesized using disproportionated rosin as raw materials. And the product was white solid with liquid chromatographic purity of 97.95% after purification. The structure and performance of N-dehydroabietic acrylamide monomer were characterized by FT-IR, MS, ¹H NMR, ¹³C NMR, TG, DSC and GPC. The characterization results showed that N-dehydroabietic acrylamide was synthesized successfully. The DSC analysis showed that the thermal polymerization of the single monomer was occurred during 151-196℃, the glass transition temperature of the polymer was 100.34℃and the polymerization temperature could be reduced with the presence of free radical initiator azodiisobutyronitrile (AIBN). The TG analysis showed that the thermal decomposition of the polymer occurred at 209-483℃. The M_n of homopolymer of N-dehydroabietic acrylamide polymerization was 4301 and M_w/M_n was 1.56 from the GPC analysis.
