A rubber composition having improved processability and which provides a vulcanized rubber exhibiting excellent wear resistance and good tensile strength to service temperatures of up to about 150° C. The composition comprises (1) a crosslinked polymer particle having as repeat units (a) up to about 25% of a conjugated diene unit, (b) at least 70% of an aromatic vinyl unit, (c) about 15% to about 30% of a crosslinking monomer, and (d) about 0.1 to about 30% of a monomer unit having one polymerizable unsaturated group and at least one functional group; and, (2) a non-crosslinked host polymer comprised of at least one member of the group consisting of a polymer having only conjugated diene repeat units, a polymer having repeat units of a conjugated diene unit and an aromatic vinyl unit, a polymer having repeat units of a conjugated diene unit and an alpha-beta-unsaturated nitrile unit, an acrylic rubber, a polymer having repeat units of an ethylene unit, and polymers having repeat units having functional groups able to interact with a functional group of the functionalized monomer.

The present invention provides an anisotropic conductive film for testing an electronic component, which comprises a film substrate comprising an insulating resin and plural conductive paths insulated from each other and penetrating the film substrate in the thickness direction, preferably, an anisotropic conductive film wherein the plural conductive paths are disposed in a houndstooth check pattern and the distance between conductive paths between adjacent rows of conductive paths is smaller than the distance between conductive paths within a row of conductive paths. In another preferable embodiment, the insulating resin comprises a naphthalene skeleton epoxy resin crosslinked with a phenol resin and an acrylic rubber, and both ends of the plural conductive paths are exposed on both the front and the back surfaces of the film substrate.
