中文摘要：

辛基酚聚氧乙烯醚（10）（OP-10）与马来酸酐在95℃下反应,合成了辛基酚聚氧乙烯醚马来酸单酯（OPMA）;并在水溶液中与丙烯酰胺（AM）单体进行共聚合,获得了高分子表面活性剂P（AM-co-OPMA）;考察了引发剂用量、单体组成、单体总浓度及反应温度对共聚物特性粘数与阴离子度的影响.通过红外光谱、紫外光谱、荧光发射光谱和电导滴定对共聚物结构和组成进行了表征;利用视频光学接触角测量仪分别测定了共聚物表面和界面张力.结果表明,在聚丙烯酰胺分子主链上引入OPMA链节后,不仅保持了PAM优良的增稠能力（特性粘数达764.31 mL/g）,且赋予了共聚物较高的表面活性（浓度为1.5 g/L共聚物水溶液的表面和界面张力分别可达53.94 mN/m和5.41 mN/m）.

英文摘要：

A surface active macromonomer of nonylphenol polyoxyethylene ether maleate （OPMA） was prepared with nonylphenol polyoxyethylene ether （OP-10） and maleic anhydride at 95 - 100℃. Copolymer surfactants of acrylamide （AM） and OPMA were synthesized in aqueous solutions with potassium persulfate （K2S2 O8 ） and sodium bisulfite （NaHSO3） as initiators. The effects of the amount of initiator, OPMA mole fraction in total monomer, total monomer concentration and reaction temperature on intrinsic viscosity and the degree of anion （DA） of copolymers were investigated. The structure and composition of the copolymers were characterized by FTIR spectroscopy, UV spectroscopy, fluorescence emission spectroscopy and conductometric titration. Surface tension and interface tension between kerosene and copolymer aqueous solutions were measured by an optical contact angle measuring device. The experiment results indicated that the polymer of PAM incorporated by OPMA segments exhibited good thickening ability and surface activity due to the strong surface active nonylphenol polyoxyethylene ether groups. The results also showed that the intrinsic viscosity of copolymers reached a maximum value of 764.31 mL/g and DA of copolymer 5.6% when the reaction took 6 h under 35℃（2,0.06 wt% initiator concentration,0.02 OPMA mole fraction in total monomer and 16 wt% total monomer concentration. The surface tension and interface tension between kerosene and 1.5 g/L copolymer aqueous solution were 53.94 mN/m and 5.41 mN/m, respectively when DA of copolymers was between 2% and 4%. In a word, the intrinsic viscosity and DA of copolymers were strongly influenced by the reaction conditions and the surface activity of copolymers first decreased and then increased with increasing its DA. These copolymers with good thickening ability and surface activity could be used in enhanced oil recovery.
