摘要: This paper describes the investigation of behavior polyelectrolyte thermosensitive hydrogels based on copolymers N-isopropylacrylamide and sodium vinylsulfonate at different temperatures. The influence ionogenic groups swollen gel-collapsed gel phase transition was studied by means highly sensitive differential scanning calorimetry. It demonstrated that presence in copolymer influences reversibility amplitude collapse, as well temperature, enthalpy, increment heat capacity.
