A kind of tripolymer was synthesized from maleic anhydride(MA),acrylamide (AM) and hexadecyl methacrylate. And then the tripolymer was alcoholyzed by cetyl alcohol.At last the diesel pour point depressant was obtained by purifying. The influence of initiator dosage, reaction time, monomer ratio and reaction temperature on degradation effect of synthesized depressant was investigated. The results show that the best reaction conditions are as follows:n(MA)︰n(AM) ︰n(HM)=1︰4︰4, intiator dosage 1.5%, polymerization reaction time 7 h,polymerization temperature 85 ,alcoholysis temperature 120℃ ℃.The pour point depressant synthesized under above conditions has good effect on 0#diesel distillate from Fushun petrochemical company.
