    摘要: A sulfur vulcanizing system rubber composition comprises EPDM, zinc as a vulcanization accelerator activator, at least one thiazole type vulcanization accelerator serving to control the dissolution of zinc from the composition, and at least one ultra-accelerator of the thiuram or dithiocarbamate type, these accelerators being preferably combined under specified quantitative limitations. The hose using this rubber composition is particularly suitable for use in a cooling system for an automobile engine, since the dissolution of zinc into a coolant is prevented, thereby preventing the formation of any zinc compound causing the blocking of the hose, or the leakage of the coolant through the seal between the hose and any pipe connected therewith.

    摘要: Novel polymer compositions for controlling or correcting dispersion mismatch between the composition and a side-fiber polished optical fiber are disclosed. The polymer compositions contain an infrared absorbing dye having an absorption maximum from about 900 to about 1200 nm and and a polar olefin copolymer containing monomers which are formed from polar olefins having an ester, benzene, or halogen substitutent attached. A method for controlling the dispersion exhibited by the novel polymer compositions is also disclosed. The method includes forming the polymer composition over an exposed surface of an optical fiber. Dispersion is controlled by controlling the amount of dye present in the polymer composition. Also disclosed is an optical device from which improvements in the uniformity of spectral response and performance are observed across a wavelength band. The optical device includes the polymer composition formed over an optical fiber. Variable optical attenuators, switches, and couplers can be designed which incorporate the polymer compositions. The invention is particularly useful in the 1500-1600 nm wavelength band.

    摘要: A peroxide cure system rubber composition comprises EPDM having a high iodine value and an appropriate ethylene proportion, and preferably at least quinoline as an antioxidant, and is particularly suitable for use in making a hose in a cooling system for an automobile engine. The hose is highly resistant to hot air aging and cracking, though the composition does not contain zinc.
