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.
