Abstract: (2-Methylacryloyloxy)ethyl ester of acrylic acid modified rosin (AR-2-HEMA) was synthesized by esterification of carboxyl group in acrylic acid modified rosin(AR)and characterized by using FT-IR spectroscopy, GC-MS,13C NMR spectroscopy and DSC. The results showed that AR-2-HEMA is composed of (2-methylacryloyloxy)ethyl ester of acrylopimaric acid (AHR-2-HEMA, 37.88%) and (2-methylacryloyloxy)ethyl ester of resin acids (52.88%).(2-Methylacryloyloxy)ethyl ester of acrylopimaric acid is an isomer and the mass fractions of two structure are 31.79% and 6.09%, respectively. AR-2-HEMA can polymerize in the presence of initiators.

Key words: acrylic acid modified rosin, (2-methylacryloyloxy)ethyl ester of acrylic acid modified rosin, polymerizability
