摘要：

N-Isopropylacrylamide (NIPAAm) was graft polymerized from its acetone solution onto poly(propylene) (PP) films, after electron beam irradiation in the presence of air oxygen. The effects of pre-irradiation dose as well as monomer concentration reaction temperature and reaction time on the grafting efficiency were investigated. Typical conditions for achieving maximum grafting yield were observed for 1 M monomer concentration, after PP pre-irradiation with a 300 kGy dose and a reaction temperature of 50 degrees C. The location of the graft polymerization was examined by the different methods including measurements of dimensional variations, calorimetry, SEM and AFM. The temperature-responsive behaviour of grafted copolymer was studied by swelling and contact angle measurements at different temperatures.
