Described herein are compositions comprising the reaction product of a polyol, a multi-functional isocyanate, a lactone-acrylate adduct and an hydroxyalkyl acrylate. These compositions are suitable for use as curable coatings.

Coating compositions prepared from lactone-acrylate adduct, polyol and

Graft copolymers are obtained which are substantially free of insoluble homopolymers by grafting 3 to 15 percent by weight of acrylic acid onto poly(oxyalkylene) compounds.

Carboxylated poly(oxyalkylenes)

Amphoteric acrylic-based latexes are produced by the imination of from about 25% to about 75% of the carboxylic sites of base polymers latexes having an acrylic acid and/or methacrylic acid content of from about 10 to about 35 weight percent, based on the total weight of monomers employed in such base polymers.

Amphoteric acrylic ester based latexes

Fluid, stable polymer-polyols are provided which consist of an organic polyol medium and an interpolymer of a minor amount of polymerized ethylenically unsaturated dicarboxylic acid anhydride, such as maleic acid anhydride, and a major amount of at least one different polymerized ethylenically unsaturated monomer, the interpolymer being in the form of particles that are stably dispersed in the polyol. Polyurethane foams produced from these polymer/polyols display improved load bearing and compression set when compared with polymer/polyols produced in a similar manner without the ethylenically unsaturated dicarboxylic acid anhydride; elastomers so produced have improved tensile modulus and tear properties.
