    Abstract: 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.

    Abstract: 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.
