Abstract: Power transmission belts described herein have a nitrile group-containing copolymer rubber that has an acrylonitrile unit, a monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile, and a conjugated diene monomer unit. The nitrile group-containing copolymer rubber has an iodine value of 120 or less a total of the acrylonitrile unit and the monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile is 1 to 50% by weight in the total monomer unit, and a weight ratio of the acrylonitrile unit and the monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile is 10:90 to 90:10.

Abstract: A power transmission belt having a body made of a first elastomeric material, a plurality of cords embedded in the body of the belt, a back and a plurality of ribs or teeth. The back or the ribs or the teeth are covered by a covering material chosen from the group composed of woven fabric and knitted fabric. The covering material includes elastolefin fibres, and preferably at least one elastolefin thread.
