摘要： The invention provides a copolymer which comprises, as essential components, 25-75 mol % of a fluoroolefin such as CTFE, 10-70 mol % of a carboxylic acid vinyl ester, 3-75 mol % of a hydroxyl-containing allyl ether and 0.1-20 mol % of an unsaturated carboxylic acid having at least 6 carbon atoms in the molecule. The copolymer is soluble in various organic solvents and curable, e.g., with a blocked polyisocyanate or a modified melamine resin. The copolymer can be prepared by a suspension polymerization method in an aqueous medium and hence can be made very low in the contents of unreacted residual monomers. The copolymer is very suitable for use in electrodeposition paints.

摘要： The invention provides a novel copolymer comprising 25-75 mol % of a fluoroolefin such as CTFE or TFE, 10-70 mol % of an alkene such as ethylene or propylene, 3-40 mol % of a hydroxyl-containing allyl ether such as ethylene glycol monolallyl ether and 0-20 mol % of a carboxyl-containing monomer such as vinylacetic acid. This copolymer possesses favorable properties characteristic of fluororesins, is soluble in organic solvents including aromatic solvents low in polarity, such as xylene, and is curable at relatively low temperatures. The copolymer is useful particularly as a paint vehicle. The water repellency of the copolymer in cured state can be enhanced by incorporating a fluorine-containing surface modifier in the copolymer.

摘要： A polymer blend of 2-80 wt % of an acrylic or methacrylic ester base polymer and the balance of a ternary copolymer of vinylidene fluoride (VDF), hexafluoroacetone (HFA) and tetrafluoroethylene (TFE) is very high in transparency and serves as a thermoplastic resin useful for optical purposes. The first polymer of the blend can be selected from homopolymers and copolymers of C.sub.1 -C.sub.4 alkyl acrylates and methacrylates. The second polymer is preferably made up of 2-15 mol % of HFA, 5-60 mol % of TFE and the balance of VDF. The polymer blend has a relatively low index of refraction, which can be controlled by selecting the first and second polymers and/or by varying the blending ratio. The polymer blend is soluble in various organic solvents. Besides, the polymer blend serves as a thermochromic material that becomes opaque by heating and resumes transparency by cooling.

摘要： The invention provides an adhesive for bonding together a first substrate made of a polyvinylidene fluoride resin and a second substrate. This adhesive includes an elastic fluorohydrocarbon resin, an acrylic resin, a polyvinylidene fluoride resin, a polyisocyanate, and an organic solvent. This elastic fluorohydrocarbon resin is obtained by graft copolymerization of a fluorine-containing copolymer with a vinylidene fluoride monomer. This copolymer is prepared by copolymerizing at least one first fluorine-containing monomer with at least one unsaturated monomer that has peroxy bond. The adhesive itself is superior in durability, and bond strength between the first and second substrates is also superior.
