Radiation-induced grafting of 2,3-epoxypropyl methacrylate on polypropylene fabric, and amination onto the copolymers

The grafting of 2,3-epoxypropyl methacrylate on polypropylene fabric was carried out by the gamma-ray preirradiation grafting technique. The grafting extent was found to be dependent on the storage condition of the irradiated polypropylene fabric, the preirradiation dose, the reaction time and temperature, and the addition of solvent. 2,3-Epoxypropyl methacrylate-grafted polypropylene fabric was reacted with ammonia and various types of amines for different reaction times and temperatures. The amination extent followed the order dimethyl amine, trimethylamine > methylamine > ammonia.
