    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.

    Abstract: Bridged dense star polymers having terminal group densities greater than conventional extended star polymers exhibit greater and more uniform reactivity than their corresponding conventional star polymers. For example, a third generation, hydroxy-terminated polyether dense star polymer can be prepared from pentaerythrityltetrabromide and 4-hydroxymethyl-2,6,7-trioxabicyclo[2.2.2]-octane which has a molecular volume less than 80 percent of the volume of a conventional extended star polymer made from similar materials. This dense star polymer can then be bridged by reacting it with a suitable difunctional reactant such as toluene diisocyanate. Such polymers of dense star polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, calibration standards for electron microscopy, and agents for modifying viscosity in aqueous formulations such as paints.

    Abstract: Dense star polymers having terminal group densities greater than conventional star polymers exhibit greater and more uniform reactivity than their corresponding conventional star polymers. For example, a third generation, amine-terminated polyamidoamine dense star polymer prepared from ammonia, methyl acrylate and ethylenediamine has 1.24.times.10.sup.-4 amine moieties per unit volume (cubic Angstrom units) in contrast to the 1.58.times.10.sup.-6 amine moieties per unit volume contained by a conventional star polymer. Such dense star polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, and agents for modifying viscosity in aqueous formulations such as paints.
