The N-benzylmaleimide( NBMI) was produced by maleic anhydride and benzene methanamine. And the oil-soluble heavy oil viscosity reducer was synthesized by solution polymerization with octadecyl methacrylate,acrylic acid and the prepared N-benzylmaleimide. The chemical structure and composition of the copolymer was identified by IR spectrum. The optimum reaction conditions were obtained as follow:n(octadecyl methacrylate)∶n(acrylic acid)∶n(N-benzylmaleimide) =8∶2∶2,the initiator dosage was 1. 2%,polymerization temperature was 75℃,and the reaction time was 5 h. Further,the viscosity was de-creased from 4 360 mPa · s to 873 mPa · s when the dosage of viscosity reducer was 1 000 mg/L at 50 ℃.
