<p>A copolymer of an unsaturated fluoro compound with a vinyl ether and, optionally, with at least one additional ethylenically unsaturated monomer can be stabilized against gelling by the addition, either to the copolymerization reaction or to the copolymer in solution or in aqueous dispersion, of a 2,2-unsubstituted alicyclic 1,3-diketone in the presence of the enolate ion of said ketone, which enolate may be formed in situ. Solutions and dispersions of such copolymers are very useful in hard, weather-resistant finishes, for example, those used for bridge ironwork and architectural maintenance and in automotive applications.</p> |
