    摘要： The present invention is directed to partially fluorinated copolymers and the production thereof. More specifically, the copolymers, which are preferably produced by a solution polymerization process, preferably have at least three units, the first unit selected from 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene, the second unit having a polymerized monomer selected from the vinyl esters and vinyl ethers, and the third unit having a polymerized monomer derived from a hydroxyl group-containing vinyl ether. The resulting copolymer is environmentally friendly, has favorable molecular weight characteristics, and may be shipped economically in high concentration.

    摘要： Methods of reducing the release of volatile organic compounds (VOCs) into the Earth's atmosphere during coating operations are provided, as well as a coating composition comprising a carrier and one or more fluorocopolymers. The carrier comprises VOC compounds and the one or more fluorocopolymers is produced by copolymerization of (1) a first monomer selected from the group consisting of hydrofluoroalkenes, (2) a second monomer comprising vinyl ester(s), and (3) a third monomer comprising vinyl ether(s), wherein at least a portion of the vinyl ether monomer is a hydroxyl group-containing vinyl ether, and wherein the one or more fluorocopolymers comprise at least about 70% by weight of the coating composition and the VOC portion of the carrier is not greater than about 30% by weight of the coating composition.
