Abstract: The invention relates to compositions of hydroxyl functional acrylic resins (acrylic polyols) comprising a mixture of α,α-branched alkane carboxylic glycidyl esters derived from butene oligomers characterized in that the sum of the concentration of the blocked and of the highly branched isomers is maximum 55%, preferably below 40%, and most preferably below 30% weight on total composition.

Abstract: The invention relates to compositions of glycidyl ester used as a stabilizer in polyurethane foams formulations having a good resistance to hydrolysis, improved damping with equivalent or improved physical properties, and high sound absorption capacity. The mono or poly-carboxylic acids glycidyl ester is used in amount of 0.1 to 10 weight % over the polyester polyol resin.

Abstract: The invention relates to compositions of glycidyl ester in C9 to C15 branched acid is with a concentration in compounds, which have a boiling point below 250° C., of less than 8000 ppm. Such a composition are specially useful as stabilizer of thermoplastic extruded polymer; It has been demonstrated that such composition are generating low or’ no unpleasant odour at the outlet of the extruder.
