Abstract
The present invention provides an ionizing radiation irradiated rubber molded product and a process for preparing the same, the rubber molded product being prepared by irradiating with an ionizing radiation a preform comprising 5 to 95% by weight of a fluororubber containing vinylidene fluoride copolymerized therein in a proportion of 45 to 88 mole % and having a number average molecular weight of 5,000 to 200,000, and 95 to 5% by weight of an acrylic rubber.
Claims7
A rubber molded product obtained by irradiating with an ionizing radiation in a dose of 5 to 500 kGy a preform comprising 5 to 95% by weight of a fluororubber containing vinylidene fluoride copolymerized therein in a proportion of 45 to 88 mole % and having a number average molecular weight of 5,000 to 200,000 and 95 to 5% by weight of an acrylic rubber.
A process for preparing a rubber molded product by preforming a composition comprising 5 to 95% by weight of a fluororubber containing vinylidene fluoride copolymerized therein in a proportion of 45 to 88 mole % and having a number average molecular weight of 5,000 to 200,000, and 95 to 5% by weight of an acrylic rubber, and irradiating the preform with an ionizing radiation.
