Abstract Thermo- and pH-responsive statistical copolymers of N-(dimethylamino)ethyl methacrylate and lauryl methacrylate were synthesized by free radical copolymerization. Obtained samples differed in content of hydrophobic components (3 and 6 mol. %). Their molar masses were close to 30,000 g/mol. Self-organization in buffer solutions of copolymers were studied using light scattering and turbidimetry. It was found that copolymers as well as of poly(N-(dimethylamino)ethyl methacrylate) were thermosensitive at pH > 7. Phase separation temperatures of investigated solutions decreased with dilution and pH increasing. Growth of lauryl methacrylate content in copolymers caused the decrease in phase separation temperatures.

基于甲基丙烯酸 N-(二甲氨基)乙酯的热敏统计共聚物水溶液中的自组织

摘要 通过自由基共聚反应合成了甲基丙烯酸N-(二甲氨基)乙酯和甲基丙烯酸月桂酯的热响应和pH响应统计共聚物。获得的样品在疏水组分的含量上不同（3 和 6 mol.%）。它们的摩尔质量接近 30,000 g/mol。使用光散射和浊度法研究了共聚物缓冲溶液中的自组织。发现共聚物以及聚（N-（二甲基氨基）乙基甲基丙烯酸乙酯）在 pH > 7 时对热敏感。研究溶液的相分离温度随着稀释和 pH 的增加而降低。共聚物中甲基丙烯酸月桂酯含量的增加导致相分离温度的降低。
