摘要:
A shaped article having a thermal recovery property comprising a urethane resin composition, wherein said urethane resin composition comprises 100 parts by weight of a thermoplastic urethane resin and from 0.1 to 50 parts by weight of at least one polyfunctional monomer selected from the group consisting of trimethylolpropane triacrylate, trimethylolpropane trimethacrylate, and triacrylformal, said composition is irradiated with electron beams or gamma-rays for a total dose of from 3 to 50 Mrad, subsequently deformed at a temperature not lower than the softening point of said composition, and then cooled to a temperature lower than said softening point while maintaining the deformed shape of said resin composition.
