摘要:
Thermoplastic compositions useful as molded parts including automotive hoses and exterior body parts which exhibit good flow and good surface characteristics in injection molded parts. The compositions comprise equal proportions of a polyolefin, a halogenated butyl rubber and polychloroprene wherein the rubbers have been dynamically vulcanized to a fully cured state in the presence of the polyolefin.
摘要:
The heat-aging properties of a halogen-containing rubber are improved by adding to the rubber, before vulcanization, an effective amount of an aromatic amino acid, a salt or ester of an aromatic amino acid, an amino phenol or a salt of hydroxy benzoic acid, or two or more such compounds and vulcanizing.

摘要:
The invention provides a novel watertight rubbery sealing material, the water-swellability of which is hardly influenced by the compression of the material in a dry condition. The watertight sealing material is a shaped and vulcanized body of a water-swellable rubber composition comprising, in a limited proportion, (a) a chloroprene rubber, (b) a highly water-absorptive resin such as a crosslinked polyacrylic acid in the form of a sodium salt, (c) a rubber polymer unvulcanizable with a metal oxide-based vulcanizing agent and (d) a metal oxide-based vulcanizing agent which is preferably a combination of magnesium oxide and zinc oxide.
摘要:
A granular composition of ethylenethiourea-chloroprene rubber is produced by adding dropwise a mixture of chloroprene rubber latex and ethylenethiourea at a ratio of 5-100 wt.% per rubber of said rubber latex and a macromolecular polyanion having carboxyl group or hydroxyl group at a ratio of 2-8 wt.% per rubber of said rubber latex lower than 10 °C into an aqueous solution containing at least one of alkaline earth metal salt at lower than 10 °C to form granule and then, dehydrating and drying the granule.
