Abstract: An acrylic composition includes the reaction product of an acrylic polymer and carbon dioxide. The acrylic polymer includes the reaction product of a functionalized monomer, a first compound reactive with the functionalized monomer to form a functionalized intermediate, and a highly branched, polyfunctional core molecule reactive with the functionalized intermediate. The first compound includes vinyl functionality reactive with the functionalized monomer. The first compound also includes epoxy functionality. The carbon dioxide is reactive with the acrylic polymer to form a carbonate-functional acrylic polymer. The acrylic composition is highly-branched and, when used in coating compositions in combination with a suitable cross-linking agent, enhances recoat adhesion and produces cured films that have optimum scratch, mar, and chip performance, and acid etch resistance.

Abstract: A binder for a coating composition is formed using a principal resin polyol, in combination with a hyper-branched polyol as a reactive intermediate, and at least one crosslinker. The principal resin polyol is at least one of a polyester polyol, a polyether polyol, and a polyacrylate. Hyper-branched polyester polyols may be used as reactive diluents, which will cross-link with isocyanates, isocyanurates, epoxides, anhydrides or their corresponding polyacids and/or aminoplasts to form a binder having particular properties, to help control the rheology of a coating system. The hyperbranched polyol, the principal resin polyol, or both may, optionally, include a carbamate functional group in the structure thereof. Coating compositions may be made using the binders together with additional components.
