Accordingly, the surface thereof can be directly treated with electroplating. Further, the use of chromic acid as a source of environmental pollution or other conventional addition agents for the surface treatment is completely eliminated.Type: GrantFiled: February 1, 1980Date of Patent: May 31, 1983Assignee: Kokoku Rubber Industrial Company LimitedInventors: Hiroshi Kuramochi, Noriaki Nakajo, Makoto Abekura, Jun Matsumoto

Patent number: 4366001Abstract: Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic radicals or carboxy-functional organic radicals or epoxy-functional radicals and the other bearing another type of organofunctional radicals selected from the same group. In addition, at least one of the organofunctional polysiloxanes bears one or more polyoxyalkylene radicals.These compositions are useful for durably treating fibers to provide several benefits such as antistatic character, moisture/perspiration absorbability, stain resistance, pliability, smoothness, crease resistance and compression recovery.Type: GrantFiled: July 2, 1981Date of Patent: December 28, 1982Assignee: Toray Silicone Co., Ltd.Inventors: Isao Ona, Masaru Ozaki

Patent number: 4347175Abstract: A method for stabilization of polymers susceptible to an oxidative destruction which comprises intermixing a polymer with formate of a multi-valent metal in an amount ranging from 0.1 to 20 parts by weight per 100 parts by weight of the polymer. The resulting mixture is subjected to a heat treatment at the temperature of decomposition of the selected formiate of variable-valency metal. The method enables the production of polymers and articles therefrom possessing high physico-mechanical properties. The method is versatile and applicable to any type of polymers susceptible to oxidative destruction.Type: GrantFiled: November 23, 1977Date of Patent: August 31, 1982Inventors: Olga A. Shustova, Georgy P. Gladyshev, Tamara P. Potapova
