摘要： An essentially linear polyester oligomer having hydroxyl and carboxyl terminal groups for subsequent cure and its production are disclosed. This polyester oligomer is produced by first adducting approximately equimolar amounts of diol carrying two primary hydroxyl groups and a dicarboxylic acid anhydride to form an hydroxy acid. The carboxyl groups of this hydroxy acid are then esterified by reaction with an approximately stoichiometric proportion of diol carrying one primary hydroxyl group and one secondary hydroxyl group, the stoichiometry being based on the total hydroxyl content of the diol and the carboxyl content of the hydroxy acid, to form an hydroxyl-terminated oligomer. This hydroxyl-terminated oligomer is then adducted with a polycarboxylic acid monoanhydride having a carboxyl functionality of at least 3, this monoanhydride being used in an amount of 0.01 to 0.15 equivalents of anhydride per hydroxyl equivalent in the hydroxyl-terminated oligomer. The resulting polyester oligomer is essentially linear and possesses low solution viscosity at high resin solids content combined with high reactivity enabling low temperature cure with aminoplast resins.

摘要： Low temperature curing aqueous coatings are provided by combining a water soluble bisphenol polyol with a branched copolymer of an unsaturated epoxy ester with monoethylenic monomers including about 3% to about 20% carboxyl-functional monomer, based on the weight of the copolymer, so that the copolymer can be dispersed in water with the aid of a volatile base. The solids content is increased or the viscosity is lowered, the curing temperature is reduced, and the corrosion resistance is enhanced by the presence of the bisphenol polyol.

摘要： Low temperature curing aqueous coatings are provided in which the resin solids are constituted by an epoxy ester of a resinous polyepoxide with at least about 0.2 mole of monocarboxylic acid containing conjugated unsaturation per epoxy equivalent in the polyepoxide and at least about 0.5 mole of monocarboxylic acid containing nonterminal nonconjugated unsaturation per epoxy equivalent in the polyepoxide. This epoxy ester is substantially free of epoxy groups and is copolymerized in solvent solution with monoethylenic monomers containing terminal unsaturation, including carboxyl-functional monomers and preferably also monomer providing a primary hydroxy group, and then precondensed with a phenolic resin to provide a non-gelled, solvent-soluble copolymer-phenolic condensate having carboxyl-functionality and residual ethylenic unsaturation. The carboxyl-functionality of the copolymer allows it to be dispersed in water with the aid of a base, and the residual ethylenic unsaturation enables an oxidative cure to supplement the cure with the phenolic resin and this minimizes curing temperature at the same time that the cure is maximized to provide better salt spray and detergent resistance than would otherwise be obtainable.
