Latest Patents

Koshita holds a patent for a fluoroolefin-based copolymer that is particularly useful in electrodeposition paints. This invention provides a copolymer that comprises essential components, including 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 with at least six carbon atoms in the molecule. The copolymer is notable for its solubility in various organic solvents and its curability with a blocked polyisocyanate or a modified melamine resin. It can be prepared through a suspension polymerization method in an aqueous medium, resulting in very low contents of unreacted residual monomers. This copolymer is highly suitable for use in electrodeposition paints.
