Date Jul. 3, 1997A branched alkenyl functional polyester of a prepolymer having at least one carboxyl and at least three hydroxyl groups, which is made allylfunctional by reaction between at least one of said hydroxyl groups in the prepolymer and at least one monomeric or polymeric compound having at least one allylic unsaturation. The prepolymer is a condensation product obtained by condensing at least one monomer selected from the group consisting of di, tri or polyhydroxyfunctional monocarboxylic acids having 2-18 carbon atoms optionally followed by further chain extension by addition of at least one monohydroxyfunctional monocarboxylic acid or corresponding lactone having 2-24 carbon atoms. |
