Polyampholyte Hydrogels Based on Aliphatic Diamines

  • Published:
Fibre Chemistry Aims and scope

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.
