Abstract: A method for producing a laminate including a substrate and a rubber layer, the rubber layer having a thickness of 200 μm or more from the surface of the substrate, the method including contacting the substrate in a heated state with a polymer latex having a viscosity of 2,000 to 100,000 mPa·s at 25° C. to thereby coagulate the polymer in contact therewith to form the rubber layer.

Abstract: Provided is a binder composition for a non-aqueous secondary battery containing: a particulate polymer formed of a block copolymer including an aliphatic conjugated diene monomer unit and a block region formed of an aromatic vinyl monomer unit; at least one saturated hydrocarbon selected from the group consisting of a chain alkane having a carbon number of not less than 5 and not more than 8 and a cycloalkane having a carbon number of not less than 5 and not more than 8; and water. The content of the saturated hydrocarbon is not less than 0.001 parts by mass and not more than 0.1 parts by mass per 100 parts by mass of the particulate polymer.

Abstract: A dip-formed article includes a laminate in which a rubber layer is laminated on a fiber base material. The thickness of the rubber layer is 0.2 to 0.8 mm, the rubber constituting the rubber layer penetrates into the fiber base material, the maximum depth to which the rubber has penetrated into the fiber base material is 0.1 to 0.3 mm, and the maximum stress at 50% elongation of the laminate is 20 N or smaller.

Abstract: A rubber formed article includes a laminate in which a rubber layer of nitrile rubber is laminated on a fiber base material. The nitrile rubber contains a copolymer having 52 to 78% by weight of conjugated diene monomer units, 20 to 40% by weight of α,β-ethylenically unsaturated nitrile monomer units, and 2 to 10% by weight of ethylenically unsaturated monocarboxylic acid monomer units. Stress at 50% elongation of the laminate is 20 N or smaller. A ratio of an area where rubber is visible when the laminate is viewed from the back side to an area of the laminate is 15% or less. The thickness of the rubber layer is 0.30 mm or less.
