Abstract: Hydroabietyl methacrylate was synthesized by the reaction of methacrylic chloride with hydroabietyl alcohol under hydroxyl-to-chloride molar ratio of 1∶1 and its stucture was characterized by FT-IR, GC/MS, ¹³C NMR , and DSC. The results showed that hydroabietyl methacrylate was mainly composed of tetraabietyl methacrylate, dihydroabietyl methacrylate, dehydroabietyl methacrylate, and a small amount of methyl hydroabietate. The total mass fraction of the prepared hydroabietyl methacrylate was 78.76 %. Hydroabietyl methacrylate could polymerize in the present of initiators and exhibited higher polymeric activity than hydroabietyl acrylate. The glass transition temperature of polymer is around -11.32 ℃, which enable hydroabietyl methacrylate to be used as internal plasticizer or reactive tackifying resin.

Key words: hydroabietyl alcohol, methacyloyl chloride, hydroabietyl methacrylate
