Abstract: Allyl ester of maleopimaric acid (MA-BXC) with a purity of 99.2% was prepared by the reaction between maleopimaric acyl chloride and allyl alcohol with the yields near to 70%. The structure and properties of MA-BXC was evaluated by FT-IR spectroscopy, GC-MS, 13C NMR spectroscopy and DSC. The results indicated that MA-BXC was an allyl monomer with anhydride group and can be polymerized while being heated to above the melting point. The glass transition temperature of MA-BXC's homopolymer is about 98℃. These results showed that MA-BXC had a great potential to be used as a precursor of unsaturated resin and epoxy resin.

Key words: maleopimaric acid, monomer, free radical polymerization, allyl ester of maleopimaric acid
