【摘要】 采用自由基胶束聚合方法合成了水溶性的聚丙烯酰胺-丙烯酸十八烷基酯疏水缔合聚合物,研究了疏水缔 合聚合物水溶液的流变性能及其影响因素。实验表明,疏水单体链节含量的增加,使聚合物的特性粘数减小,即溶 液中大分子链团的流体力学体积减小,表明疏水缔合作用增强;同时聚合物表现了明显的抗盐耐温性。更多还原

【Abstract】 <abstract>drophobic associated water-soluble polymers of poly acrylamide-acroleic octadecyl ester have been synthesized via free-radical micellar polymerization, rheologi cal properties and its influencing factors of these polymer solutions have been studied. The experiment shows that the high content of hydrophobic monomer makesthe inherent viscosity of the polymer decreases, that is, hydrodynamic volume of macromolecular chain group in the solution decreases and the hydrophobic association strengthened. At the same time, the salt resistant and temperature-resistance of the polymers are observed.更多还原
