摘　　要：通过N,N-二甲基十二胺和4-乙烯基苄氯季铵化反应合成了阳离子单体4-乙烯基苄基十二烷基二甲基氯化铵(VBDDMAC),然后与丙烯酰胺(AM)、N-丙烯酰胺吗啉(ACMO)自由基共聚,合成了不同组成的共聚物,用核磁共振、红外光谱和激光光散射对共聚物结构和分子质量进行了表征,用共振光散射对共聚物在水溶液中的聚集行为进行了考察。此外,通过界面张力和接触角研究了共聚物与原油之间的相互作用,考察了共聚物对稠油的降黏性能,发现阳离子单体VBDDMAC和ACMO的引入,使得共聚物具有较好的表面活性和乳化性能,对稠油有较好的降黏效果。The cationic monomer 4-vinylbenzyl dodecyldimethylammonium chloride(VBDDMAC) was synthesized by quatermarization of N,N-dimethyldodecylamine and 4-vinylbenzene, and then the copolymers were prepared by the copolymerization of acrylamide(AM), N-acrylamide morpholine(ACMO) and VBDDMAC. Different copolymers with different monomer ratios were synthesized. The structure of the copolymer was characterized by NMR and IR spectra. The aggregation behavior of the copolymer in aqueous solution was investigated by resonance light scattering. In addition, the interaction between the copolymer and the crude oil was investigated by interfacial tension and contact angle measurement. Finally, the viscosity reduction of the heavy oil was investigated. The results show that the cationic ingredient VBDDMAC makes the copolymer have some emulsifying properties, and the monomer ACMO enhances the interaction between polymer and heavy oil component to greatly reducing the viscosity of heavy oil.
