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 objective of the present invention is to provide a rare earth metal-based permanent magnet with improved adhesion properties. A rare earth metal-based permanent magnet of the present invention as a means for achieving the objective has a laminated plating film, and is characterized in that the plating film comprises as an outermost surface layer a SnCu alloy plating film having a film thickness in a range from 0.1 μm to 2 μm, the composition of the SnCu alloy plating film is 35 mass % or more but less than 55 mass % of Sn and the rest being Cu, and a base plating film having two or more layers including at least a Ni plating film and a Cu plating film which are formed as the lower layer under the SnCu alloy plating film, and among the base plating film, the Ni plating film is located just below the SnCu alloy plating film. A joined structure fabricated using the rare earth metal-based permanent magnet of the present invention exhibits favorable initial adhesion strength when combined with a silicone-based adhesive, and is less deteriorated in adhesion strength even after a moisture resistance test.
