Statistical copolymers of N-isopropylacrylamide containing 2.2 – 2.7 mol % D,L-allylglycine were synthesized. The sample with 2.2 mol % allylglycine and molar mass 320000 g/mol was studied using light scattering and turbidimetry while heated in water and water–salt solutions. Temperature dependencies of light scattering intensity and optical transmission as well as hydrodynamic size and composition of the scattering entities were obtained in a wide range of pH. The onset temperatures of phase separation were independent of pH; however, in the basic pH region the phase transition was widened as compared to the neutral and acid media. It was shown that a small content of allylglycine results in a different thermoresponsive behavior of the copolymer as compared with N-isopropylacrylamide homopolymer. The addition of a physiological amount of NaCl shifts the copolymer thermo-sensitivity toward lower temperatures.

N的统计共聚物合成了含有2.2 – 2.7 mol％D，L-烯丙基甘氨酸的异丙基丙烯酰胺。在水和水-盐溶液中加热的同时，使用光散射和浊度法研究了具有2.2 mol％烯丙基甘氨酸和摩尔质量320000 g / mol的样品。在宽的pH值范围内，获得了光散射强度和光透射率的温度依赖性以及散射实体的流体动力学尺寸和组成。相分离的起始温度与pH无关。但是，在碱性pH范围内，与中性和酸性介质相比，相变变宽了。结果表明，与N-异丙基丙烯酰胺均聚物相比，少量的烯丙基甘氨酸会导致共聚物具有不同的热响应性能。
