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： Aqueous dispersions of partially cross-linked copolymer particles useful in aqueous coating compositions is produced by copolymerizing in aqueous emulsion a mixture of: (A) from 1% to 30% of polyethylenically unsaturated monomer; (B) from 3% to 30% of hydroxy-functional monoethylenically unsaturated monomer; (C) from 0.5% to 10% of a salt-forming monoethylenically unsaturated monomer selected from monoethylenic carboxylic acid monomer and monoethylenic amine monomer; and (D) the balance of the copolymer consisting essentially of copolymerizable monoethylenically unsaturated monomer, preferably nonreactive monomer such as vinyl acetate. The copolymer particle-containing suspension produced by the emulsion copolymerization is coagulated with water immiscible organic solvent which is a poor solvent for the copolymer, such as butanol, to provide a liquid phase containing coagulating solvent and the water and surfactants used in the emulsion copolymerization and a coagulum of the copolymer particles in the suspension. This coagulum, after removal of the liquid phase, is dispersed in water with the aid of a salt-forming volatile acid or a volatile base and a water-miscible organic solvent, said last-named solvent being present in the aqueous dispersion in an amount insufficient by itself to dissolve the coagulum in the absence of the salt-forming acid or base.

摘要： Thermosetting aqueous anionic electrocoating composition are disclosed which comprise a carboxyl-functional anionic polymer dispersed in water with the aid of water miscible organic solvent and a volatile base, and from about 1% to about 5%, based on the weight of the polymer content of the composition, of an oxirane-free epoxy phosphate, this epoxy phosphate being produced by slowly and incrementally adding a resinous polyepoxide to a solvent solution containing from 0.05 to 0.9 mole of orthophosphoric acid per oxirane equivalent in the polyepoxide together with sufficient water to hydrolyze all of the oxirane functionality which is not consumed by the orthophosphoric acid. These epoxy phosphates improve the corrosion resistance of electrodeposited cured coatings without objectionably wrinkling their surface.

摘要： There is disclosed solution copolymers of monoethylenically unsaturated monomers including a proportion of monoethylenically unsaturated carboxylic acid, with an oxirane- free epoxy acid ester phosphate having adducted onto the oxirane groups of a starting polyepoxide at least 10% thereof of ortho phosphoric acid as well as at least 0.5% by weight of a monoester of a saturated monohydric alcohol with a monoethylenically unsaturated dicarboxylic acid which resists homopolymerization, the remaining oxirane groups of the polyepoxide being esterified with monocarboxylic acid, etherified with monoalcohol or hydrolyzed with water. These copolymers can be neutralized with a volatile amine, especially ammonia and cured with aminoplast or phenoplast resins to provide coatings which cure to greater flexibility and better resistance to blushing on pasteurization exposure.

摘要： Coating compositions which cure on baking to provide hard and flexible coatings characterized by superior abrasion resistance and mar resistance comprise:
(1) a polyol component which is an adduct of at least a stoichiometric proportion of ethylene oxide or propylene oxide with a bisphenol;
(2) a solution copolymer containing from 40% to 70% of isobutyl acrylate, 3% to 20% of hydroxy alkyl ester of a monoethylenic carboxylic acid, up to about 20% of monoethylenic carboxylic acid, and any balance consisting essentially of monomer containing a single ethylenic group and no other reactive group; and
(3) aminoplast resin.
The polyol constitutes from 20% to 40% of the three named components, the copolymer is present in an amount of from 85% to 150% of the polyol, and the balance of the three named components is the aminoplast resin. Camauba wax is present in an amount of from 0,454 to 4.54 kg (1 to 10 pounds) of wax solids per 379 liters (100 gallons) of coating composition.
When the coatings are baked, the carnauba wax blooms to the surface and resists volatilization.-

摘要： A process of producing a water dispersible epoxy phosphate-solvent mixture is disclosed which comprises heating the solvent with orthophosphoric acid to reaction temperature together with additional water so that the total amount of water is sufficient to hydrolyze at least about 50% of the oxirane functionality in the polyepoxide which is used, slowly adding a resinous polyepoxide to this heated mixture so that reaction with phosphoric acid and hydrolysis of the oxirane groups will occur simultaneously to minimize the concentration of oxirane functionality in the reaction mixture as the reaction proceeds, thus minimizing epoxy-epoxy reactions which tend to increase the molecular weight of the epoxy phosphate which is formed, and then adding volatile amine to destroy any remaining oxirane functionality and to neutralize the epoxy phosphate to provide a water dispersible epoxy phosphate-solvent mixture.
