Abstract: Water-reducible resins, neutralized resins, and derivatized resins useful for water-borne and solvent-based coatings and inks, powder coatings, and anti-corrosive coatings are disclosed. The water-reducible resins are copolymers of a vinyl aromatic monomer, a propoxylated allyl alcohol, and an acrylic acid monomer. These low-molecular-weight resins uniquely contain both hydroxyl and acid functional groups, and allow controlled curing with a variety of crosslinkers in coating systems. Coatings of the invention are useful in many applications, e.g., automotive basecoats, industrial appliance coatings, and wood finishes.

Abstract: A process for making hydroxy-functional resins based on acrylate, hydroxyalkylacrylate, and allyl monomers is disclosed. The key to the process is to add the hydroxyalkylacrylate monomer in an amount and manner effective to produce a resin that contains, without vacuum stripping, less than about 1 wt. % of residual unreacted allyl monomers. Eliminating the need to vacuum strip the allyl monomer reduces process costs and enables the synthesis of new resins. The hydroxy-functional resins are readily crosslinked with melamines, polyisocyanates, or epoxies to give thermoset polymers.

Abstract: An improved process for making vinyl aromatic/allylic alcohol copolymers is disclosed. Gradual addition of a free-radical initiator during the course of the polymerization results in a substantial increase in the polymer yield obtained compared with the yield from conventional processes in which all of the free-radical initiator is charged initially. High yields are obtained when the monomer mole ratios are adjusted to produce styrene-allyl alcohol copolymers having a hydroxyl number in the 50-150 mg KOH/g range. Copolymers made by the process are valuable coating resins.

Abstract: High-solids and powder coatings are disclosed. The high-solids coatings comprise an acrylic resin; a melamine, silane, or polyisocyanate crosslinking agent; an organic solvent; and optionally, a pigment and a crosslinking catalyst.
