    Abstract: A fluorocopolymer composed of 40 to 60 mole % of fluorolefin units, 25 to 55 mole % of vinyl ester or ether units and 5 to 25 mole % of hydroxylated vinyl ether units, wherein the intrinsic viscosity as measured in an uncured state in tetrahydrofuran is 0.01 to 0.05 dl/g and the ratio of the weight-average molecular weight to the number-average molecular weight as measured with a gel permeation chromatograph is 2.0 or less. This copolymer is excellent in weathering resistance and provides a high-solid coating material which has a good applicability and gives a coating film excellent in definition.

    Abstract: A cold curing polyurethane composition containing as a curing component an isocyanate-terminated polyurethane prepolymer prepared by reacting an organic polyisocyanate with a polyol mainly comprising a polyoxyalkylene polyol having a molecular weight of 1,500 to 15,000 per unit hydroxyl group and a total degree of unsaturation of 0.07 meq/g or less. Such a polyoxyalkylene polyol is produced preferably by the ring-opening addition polymerization of an alkylene oxide with an initiator in the presence of a double metal cyanide complex catalyst. This composition gives a highly flexible cured article by curing the same with an atmospheric moisture. The use of a high-molecular polyoxyalkylene polyol as the curing agent gives a similar highly flexible cured article. This composition is useful as a sealant or a waterproofing material.
