Popis:	A novel thermosensitive hydrogel with high mechanical strength was obtained by grafting N-isopropylacrylamide (NIPAAm) onto polypropylene using a preirradiation grafting method. The effect of radiation dose, dose rate, grafting temperature and reaction time on the grafting degree and properties of swelling-deswelling is discussed. Water absorption of the grafted polypropylene film could be switched on and off swiftly by control of temperature. The microstructure of grafted ultra thin porous PP film was studied with scanning electron microscope. (C) 1999 Elsevier Science Ltd. All rights reserved.
