An interpenetrating polymer network (IPN) hydrogel was made by the grafting of acrylamide (AAm) and acrylic acid (AAc) onto preirradiated polypropylene (PP) film. AAm and AAc were grafted onto preirradiated PP film by two times grafting reaction. Thermo-sensitive behaviors were determined. The effect of first and second reactions on the degree of grafting was studied. Trapped radicals on samples with different storage conditions and reaction conditions were determined by electron spin resonance (ESR). (C) 2000 Elsevier Science Ltd. All rights reserved.
