Claims
- 1. A water resistant radiation crosslinked molding of a urethane resin composition comprising a thermoplastic urethane resin having incorporated therein a polyfunctional monomer selected from the group consisting of trimethylolpropane triacrylate, trimethylolpropane trimethacrylate and triacrylformal.
- 2. A water resistant radiation crosslinked molding of a urethane resin composition according to claim 1, wherein said polyfunctional monomer is present in an amount ranging from 0.1 to 50 parts by weight based on 100 parts by weight of the thermoplastic urethane resin.
- 3. A water resistant radiation crosslinked molding of a urethane resin composition according to claim 1, wherein the radiation is carried out with electron beams or gamma rays which have been given in a total dose of from 3 to 50 Mrad.
- 4. A water resistant radiation crosslinked molding of a urethane resin composition according to claim 1, wherein said urethane resin composition further contains decabromodiphenyl ether and antimony trioxide.
- 5. A water resistant radiation crosslinked molding of a urethane resin composition comprising a thermoplastic urethane resin having incorporated therein a polyfunctional monomer selected from the group consisting of trimethylolpropane triacrylate, trimethylolpropane trimethacrylate and triacrylformal, which molding is an electric wire having a coating layer of said urethane resin composition formed over a conductor.
- 6. A water resistant radiation crosslinked molding of a urethane resin composition according to claim 5, wherein said conductor is composed of two or more insulated conductors which are twisted in a strand form.
- 7. A water resistant radiation crosslinked molding of a urethane resin composition comprising a thermoplastic urethane resin having incorporated therein a polyfunctional monomer selected from the group consisting of trimethylolpropane triacrylate, trimethylolpropane trimethacrylate and triacrylformal, wherein said molding is capable of withstanding a thermal deformation test of 180.degree. C. without substantially deforming.
