Abstract—

Homo- and copolymers of poly-11-acryloyloxyundecyltrimethylammonium bromide and poly-11-acryloyloxyundecylquinolinium bromide have been prepared. Molecular parameters and solubilization properties of these polyelectrolytes have been determined. Their catalytic activity in the model reaction of alkaline hydrolysis of p-nitrophenyl butyrate has been investigated. The introduction of the units containing a quinoline moiety has led to consistent growth of the solubilization capacity of the copolymer with respect to a hydrophobic dye, Orange OT. The obtained comb-like polyelectrolytes have been found prone to solubilization over the entire concentration range; they have not possessed critical micelle concentration typical for low-molecular-weight surfactants. Acceleration of the alkaline hydrolysis of the model ester by 2–3 times has been observed in the presence of even low concentration of the comb-like polyelectrolytes. The synthesized polymeric surfactants have not crystallized with the cooling of the solution, in contrast to their monomers and other cationic low-molecular-weight surfactants.

具有喹啉和三甲铵阳离子的梳状聚电解质在胶束催化中的应用

摘要:制备了聚11-丙烯酰氧基十一烷基三甲基溴化铵和聚11-丙烯酰氧基十一烷基喹啉溴化铵的同源共聚物和共聚物。测定了这些聚电解质的分子参数和增溶性能。考察了它们在对硝基苯丁酸酯碱性水解模型反应中的催化活性。引入含有喹啉部分的单元导致共聚物对疏水染料橙色OT的增溶能力持续增长。所得到的梳状聚电解质在整个浓度范围内都易于溶解;它们不具有低分子量表面活性剂典型的临界胶束浓度。即使在低浓度的梳状聚电解质存在下，模型酯的碱性水解也会加速2-3倍。合成的聚合表面活性剂与它们的单体和其他阳离子低分子量表面活性剂相比，在溶液冷却时不会结晶。
