摘　　要：以马来酸酐(M)、苯乙烯(S)与自制的丙烯酸十八醇醚酯单体(A)共聚合成了三元共聚物(MSA)型油溶性降黏剂,考察了降黏剂对RMG380船舶燃料油的降黏效果。实验结果表明,MSA的最佳合成条件为:丙烯酸十八醇醚酯、苯乙烯、马来酸酐物质的量比为5∶1∶3,反应温度为90℃,引发剂过氧化苯甲酰(BPO)的质量分数为0.6%,反应时间为6h。在降黏剂质量浓度为300mg/L、剪切速率为2 000r/min时,RMG船舶燃料油的降黏率达到66.11%以上,满足了ISO8217—2005标准中RMG380船舶燃料油的黏度要求,降黏剂对不同的船舶燃料油均具有较好的降黏效果,但随着时间的增加降黏效果逐渐减弱。The RMG380 marine fuel oil was prepared by vacuum residue,coking wax oil and ethylene tar,the oil-soluble viscosity depressant was synthesized by maleic anhydride,styrene and octadecyl acrylate （MSA）.The optimized synthesis conditions are as follows：octadecyl acrylate,styrene and maleic anhydride monomer ratio 5∶1∶3,dosage of initiator 0.6%, synthetic temperature 90 ℃,reaction time 6 h.This synthesized viscosity depressant was evaluated under the concentration of 300 mg/L and shear rate of 2 000 r/min at 50 ℃,the ratio of viscosity reduction of marine fuel oil can reach 66.11%,and meet the ISO8217—2005 RMG380 viscosity requirements of marine fuel oil.Meanwhile,this viscosity depressant was suitable for different marine fuel oil,while viscosity reducing effect gradually weakened with the increase of time.
