Polyampholyte hydrogels based on hydrolyzed polyacrylamide and aliphatic diamines (ethylenediamine and 1,3-diaminopropane) with various ratios of starting components were studied. Polyampholytes produced from a strong base and a weak acid were found to lose their sensitivity to pH and ionic composition of aqueous solutions. The degree of swelling of the polyampholyte hydrogels increased in the range 40-60°C. Increasing the temperature further initiated thermal destruction of the polymers.

基于脂肪族二胺的聚两性水凝胶

研究了基于水解聚丙烯酰胺和脂肪族二胺(乙二胺和 1,3-二氨基丙烷)的具有各种起始组分比例的两性电解质水凝胶。发现由强碱和弱酸产生的聚两性电解质对水溶液的 pH 值和离子组成失去敏感性。聚两性电解质水凝胶的溶胀度在 40-60°C 范围内增加。升高温度进一步引发聚合物的热破坏。
