Abstract: Allyl acrylate-modified rosinate was synthesized by using sodium acrylic modified rosinate(SAMR) and allyl chloride as raw materials, cetyl trimethyl ammonium bromide as catalyst, hydroquinone as polymerization inhibitor(0.2% of the mass of SAMR) and N, N-dimetylformamide as solvent(treble the mass of SAMR) under microwave irradiation.The influence of different reaction conditions on the yield of product was investigated.The optimum reaction conditions were microwave energy 400 W, reaction time 100 min, catalyst amount 4%, molar ratio of allyl chloride and sodium acrylic modified rosinate 1:1, reaction temperature 50 ℃, and the yield was 92.2% under these conditions.The structure of the product was characterized by GC, GC-MS and FT-IR.The results showed that the structure of the synthesized product and the target product was consistent.
