ON SWELLING CHARACTERISTICS AND MECHANISM OF TEMPERATURE SENSITIVE HYDROGELS*

Received Date: 8 January 1989

A series of N-substituted acrylamide monomers and the temperature sensitive hydrogels of their copolymer with N, N'-methylene-bis-acrylamide (Bis) have been synthesized. The effects of monomer structures, composition of the initial monomer mixture, polymerization temperature, the extent of ionization of the network and the presence of acid, base, salt or organic compound on the formation and the swelling characteristics of the temperature sensitive hydrogels have been systematically studied. The mechanism of the temperature sensitive phase transformation of the hydrogels was also investigated.
