摘要

Modification of poly(tetrafluoroethylene-co-ethylene), Tefzel (ETFE), film has been carried out by grafting methylmethacrylate (MMA) by radiation method including preirradiation and double-irradiation methods. Percentage of grafting has been determined as a function of the (i) total dose, (ii) monomer concentration, (iii) amount of liquor ratio, (iv) reaction time, and (v) temperature. The effect of different alcohols Such as methanol, ethanol, 2-propanol, n-butanol, n-pentanol, and 2-ethoxy ethanol on percentage of grafting of MMA was also studied. The graft copolymers were characterized by IR spectroscopy and thermogravimetric analysis (TGA). Methylmethacrylate produces higher percentage of grafting by preirradiaton method than double-irradiation method. MMA-grafted ETFE films (S-irr), i.e., prepared by preirradiation involving single irradiation show better thermal stability than MMA-grafted ETFE films (D-irr), i.e., prepared by double irradiation and unmodified ETFE film.
