摘　　要：以马来酸酐、苯乙烯、乙酸乙烯酯、十八醇为原料,采用三元共聚,通过醇解,制备了马来酸酐/苯乙烯/醋酸乙烯酯三元共聚十八酯(OMSV)。将其作为柴油降凝剂,用于改善柴油低温流动性。通过对加入OMSV的燕山石化催化加氢0#柴油的凝点和冷滤点的实验室评价,考察了OMSV的降凝效果。结果表明,当OMSV在柴油中的质量分数为0.15%时,燕山石化催化加氢0#柴油的凝点降低31℃,冷滤点降低11℃。The maleic anhydride-styrene-vlnyl acetate copolymer （MSV） was first prepared from maleic anhydride, styrene and vinyl acetate, then esterified by octadecanol and the maleic anhydrlde-styrene-vinyl acetate copolymer derivative（OMSV） was obtained. The OMSV was employed as pour point depressant（PPD） to improve the low-temperature fluidity of the 0# diesel fuel from Beijing Yanshan Petrochemical Company Limited. The result indicated that the solidification point（SP） and the cold filter plugging point（CFPP） were affected largely by OMSV, and when the mass fraction of OMSV in diesel fuel was 0.15%, the SP reduced by 31℃, the CFPP reduced by 11℃ simultaneously.
