摘要：
A two-step method for introducing acrylic functions into high molecular weight natural resins, under mild conditions, without the risk of gellation, wherein an acrylated natural resin ester is prepared by esterifying one or more of the sterically hindered hydroxy groups of the natural resin ester in an inert solvent with a 3-halopropionic acid, to form a 3-haloproprionate ester of the natural resin ester and dehydrohalogenated the 3-halopropionate ester by reacting it with an organic base.
