以对－甲苯磺酸为催化剂，甲苯为溶剂，直接酯化法制备了富马酸双十八醇酯单体（ＤＯＦ）和富马酸双混合醇酯单体（ＤＢＦ）．游离基聚合合成了富马酸双十八醇酯与醋酸乙烯酯的共聚物Ｐ（ＤＯＦ－ＣＯ－ ＶＡ）及富马酸双混合醇酯与醋酸乙烯酯的共聚物 Ｐ（ＤＢＦ－ＣＯ－ＶＡ）．单体及共聚物用 ＩＲ、~１Ｈ－ＮＭＲ等进行了表征．同时考察了共聚物对几种高蜡、高粘原油及渣油的降凝、降粘作用。
Di-octadecyl fumarate monomer (DOF) and fumaric acid dibasic alcohol ester monomer (DBF) were prepared by direct esterification using p-toluenesulfonic acid as catalyst and toluene as solvent. The copolymer P (DOF-CO-VA) of dioctadecyl fumarate and vinyl acetate and the copolymer P of dibasic fumarate and vinyl acetate (DBF-CO-VA ). Monomers and copolymers were characterized by IR, ~ 1H-NMR and so on. At the same time, the effects of copolymer on pour point depressing and viscosity reduction of several high wax, high viscosity crude oil and residue were investigated.
