摘要
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和富马酸双混合醇酯单体，游离基事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。
Dialkylfumarate-dioctadecyl fumarate and dibehenyl fumarate were synthesized by direct esterification of acid and alcohol. Dioctadecyl fumarate-vinyl acetate copolymer and dibehenyl fu- marate-vinyl acetate copolymer were obtained by free radical copolymerization with BPO as initiator. The structure of monomer and copolymer were confirmed by IR and ~1H-NMR. The obtained copolymers can be used as pour-point depressants for viscos oil and residue oil.
