摘要： The polymeric ingredient of the inventive rubber composition is an acrylic polymer modified with a mercapto-containing organopolysiloxane as prepared by the emulsion polymerization of an acrylic monomer in an aqueous emulsion of the organopolysiloxane. Characteristically, the acrylic monomer is copolymerized with another monomer having an active halogen atom or an epoxy group. By virtue of this unique formulation of the rubbery polymer, the inventive rubber composition prepared by compounding the rubbery polymer with a reinforcing filler and a specified curing or crosslinking agent can be vulcanized to give a vulcanizate having excellent mechanical properties, heat resistance, oil resistance and cold resistance as a combination of the features of silicone rubbers and acrylic rubbers.

摘要： A rubber composition based on a rubbery polymer and a silica-based reinforcing filler can be imparted with a greatly improved workability in roll milling and molding as well as in the mechanical properties of the vulcanizates prepared therefrom when the rubber composition is admixed with an acetylene alcohol or an alkylene-oxide adduct of acetylene alcohol presumably by virtue of the improvement in the dispersibility of the reinforcing filler in the rubbery matrix. The improvement obtained by the addition of the acetylene alcohol compound is not limited to the dispersibility of silica fillers but also to the dispersibility of carbon black when the rubbery polymer is an organopolysiloxane-modified acrylic polymer.

摘要： An acrylic rubbery polymer having remarkably improved cold resistance can be prepared by modification with an organopolysiloxane by the emulsion copolymerization of a monomeric mixture of two acrylic monomers, of which one is, for example, an alkyl acrylate and the other is an acrylic compound having, in a molecule, at least one ethylenically unsaturated group other than acrylic group in an aqueous emulsion of an organopolysiloxane having a substantial amount of mercapto-substituted monovalent hydrocarbon groups bonded to the silicon atoms.

摘要： Rubber vulcanizates having excellent oil resistance, heat resistance and cold resistance can be obtained from a rubbery copolymer which is a polymerization product of an acrylic monomer mixture of which the essential components are an organosiloxy-containing acrylate compound such as acryloxymethyl pentamethyl disiloxane and 3-acryloxypropyl pentamethyl disiloxane and an epoxy group- or halogen-containing monomer such as allyl glycidyl ether, glycidyl methacrylate and vinyl chloroacetate, optionally, with addition of an acrylate ester monomer such as ethyl acrylate, n-butyl acrylate and 2-methoxyethyl acrylate.
