A phase transfer catalysis （PTC） reaction was studied to synthesize allyl resinate from sodium resinate and allyl chloride, in which the factors influencing the yield of the reaction, such as reaction temperature, reaction time, catalyst type and dosage, amount of solvent and molar ratio were investigate. Under the optimum reaction conditions： reaction temperature 45 ℃, molar ratio of sodium resinate to allyl chloride 1 ： 2.5, amount of catalyst hexadecyl trimethylammonium bromide 3% based on the sodium resinate, and reaction time 7 h, the yield of product was 90.2% with purity of 98.92% （CJC）. The structure of product was characterized by IR and GC-MS.
