PURPOSE:To obtain the titled radiation-crosslinked molding excellent in hot water resistance, heat resistance and abrasion resistance, by irradiating a molding of a composition comprising a thermoplastic urethane resin, trimethylolpropane triacrylate, etc., with electron beams or the like. CONSTITUTION:A molding of a composition prepared by mixing 100pts.wt. thermoplastic urethane resin with 0.1-50pts.wt. trimethylolpropane triacrylate, trimethylolpropane trimethacrylate or triacrylformal is irradiated with electron beams or (R)-rays at a dose of 3-50 Mrad to obtain the titled radiation- crosslinked molding which can be used even at a temperature of as high as 180 deg.C or above. |
