Preparation of Styrene/Maleic Anhydride/Acrylamide Copolymer Pour Point Depressant

Chen Ma

Abstract

A styrene / maleic anhydride / acrylamide copolymer as pour point depressant for crude oil of Liaohe is synthesized through organic copolymerization.The analysis of copolymerization feasibility ,the proper ratio of monomers,the monomer's concentration and the effect of acrylamide are found to obtain copolymers with highest pour point depressing.It is shown that the pour point of Liaohe crude oil is lowered by 14 ℃.
