Lipase-mediated acrylation has gained much attention instead of traditional chemical process, since it enables specific catalysis under benign conditions. The effect of acyl donors on the acrylation of 2-hydroxy-${gamma}$-butyrolactone by Novozym 435 (immobilized lipase B from Candida antarctica) was investigated. Among acyl donors, vinyl methacrylate was selected to synthesize ${gamma}$-butyrolactone methacrylate (GBLMA). The effects of solvent and reaction temperature on the acrylation using vinyl methacrylate were presented. The highest rate of conversion was obtained using methyl tert-butyl ether (>80%) as a solvent, of which a log P value is greater than other solvents tested. The conversion rate increased as the reaction temperature rose from 30 to $60^{circ}C$ and the conversion rate approached 95% at $60^{circ}C$. The gamma butyrolactone methacrylate (GBLMA) synthesized with vinyl methacrylate at optimized conditions, in which MTBE is used as a solvent and the reaction is carried out at $60^{circ}C$ can be applicable as a monomer for synthesis of photoresist resin.
