摘　　要：以进一步提高耐温抗盐性能和降低所引入疏水基团的负面影响为设计目标,设计了主链采用C-C键连接、刚性的苯环结构作为间隔基团、采用─O─键连接聚合物的主链和疏水基团的新型疏水缔合聚合物的分子结构;通过合理选择疏水基团、间隔基团和键接方式,设计出了满足分子间缔合比例要求的非离子型疏水单体ANPE(Allyl-(4-Nonyl)Phenyl Ether);采用相转移催化法,且以低毒性的丙酮代替苯作为有机溶剂合成了疏水单体ANPE;对AM、AA和疏水单体ANPE进行三元胶束共聚合,获得了分子间高缔合比例疏水缔合聚合物(ANPE-HAWP);红外和紫外表征谱图证明了疏水单体ANPE和疏水缔合聚合物(ANPE-HAWP)的分子结构。In order to achieve the objects of high-ratio inter-molecular association molecular design,a new hydrophobically associating water-soluble polymers(HAWP)is designed by choosing hydrophobical content,spacer and chemical bond between main chain and its hydrophobic contents properly.A new nonionic hydrophobical monomer ANPE(Allyl-(4-Nonyl)Phenyl Ether)that meets high-ratio inter-molecular association requirement is designed.The monomer ANPE is synthesized through phase transfer catalyzing process and a much lower virulence solvent which is acetone instead of benzene is used.IR and UV spectrum are used to characterize these two monomers.A nonionic hydrophobically associating copolymer(ANPE-HAWP)with high-ratio inter-molecular association composed of acrylamide(AM),crylic acid(AA)and a low amount of ANPE is prepared through micellar free radical copolymerization process.IR and UV spectrum are used to characterize the monomer ANPE and the terpolymer ANPE-HAWP.
