3 ,3′‐(1 ,1′‐Diphenyl‐4 ,4′‐diyl)‐bisacrylic acid was synthesized by Heck reaction with diiodobiphenyl and acrylic acid as raw materials ,and chitosan‐supported palladium as catalyst . Also ,some factors including temperature and time were investigated to find the optimum con‐dition of the reaction .It was found that the yield could be improved if the reaction was per‐formed at 100 ℃ for 20 h and the ratio of raw materials was 1∶3 .The properties of the cata‐lyst for repeated use were investigated .And the product was characterized by IR、1 H NMR and MS .
