Abstract
A release material of a good release property is prepared by shaping a resin composition comprising a thermoplastic polyolefin resin, a dimethylpolysiloxane and a functional compound, irradiating the shaped composition with electron beams, and if desired, heat-treating the shaped composition.
Claims19
A process for the preparation of a release material comprising a substrate and a film laminated onto the substrate, which comprises melt-extruding a composition onto said substrate to form the film laminated onto the substrate, said composition comprising a thermoplastic polyolefin resin, a dimethylsiloxane and a polyfunctional compound having at least two vinyl groups, at least two methacryloyl groups or at least two thiol groups, and irradiating the laminated film with electron beams.
