摘　　要：分析油溶性降粘剂的降粘机理,研究不同单体(丙烯酸十八酯、苯乙烯、马来酸酐)对降粘效果的影响,并通过控制单体比例,设计并合成多种三元共聚物型油溶性降粘剂.测试结果表明:当单体比例不同时,效果差距明显;当单体比例为6∶2∶1时,可以得到效果较好的产品;当降粘剂浓度在0.01%时,降粘率达到40%以上,并在较长的一段时间内效果稳定.By analyzing the mechanism of oil-soluble viscosity reducer,we investigated the viscosity reduction effect of monomer（octadecyl acrylate,styrene,maleic anhydride）,and synthesized a variety of oil-soluble copolymer as viscosity reducers.The results show that the product is better by the controlling the monomer ratio.When the monomer ratio was 6∶2∶1 and the concentration of viscosity reducer was 0.01%,the viscosity reduction rate is 40% or more,and stability of viscosity reduction effect is well.
