Abstract
An interpenetrating polymer network (IPN) hydrogel was made by the grafting of acrylamide (AAm) and acrylic acid (AAc) onto preirradiated polypropylen e (PP) film. AAm and AAc were grafted onto preirradiated PP film by two tim es grafting reaction. Thermo-sensitive behaviors were determined. The effec t of first and second reactions on the degree of grafting was studied. Trap ped radicals on samples with different storage conditions and reaction cond itions were determined by electron spin resonance (ESR). (C) 2000 Elsevier Science Ltd. All rights reserved.
