Abstract

In the study hydrogels poly(acrylamide) based with different concentration of N,N’-methylenebis(acrylamide) as a crosslinker agent were prepared using a redox polymerization system. The observations on equilibrium swelling and thermal analysis are related with the thermoresponsive character. This aspect is in relation with the copolymer destination as an inner material for cold therapy packs..
