Abstract
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.
