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.

Polyester-polyol compositions for polyurethane foam with improved hydrolytic stability

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&#xb0; 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.

Odorless polyester stabilizer compositions

The invention relates to compositions of &#x3b1;,&#x3b1;-branched alkane carboxylic acids glycidyl esters with a define isomeric composition where the sum of the concentration of the blocked and of the highly branched isomers is at least 50%, preferably above 60% and most preferably above 75% on total composition.

Glycidyl esters of alpha, alpha branched acids compositions

The invention relates to compositions of hydroxyl functional acrylic resins (acrylic polyols) comprising a mixture of &#x3b1;,&#x3b1;-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 at least 50%, preferably above 60% and most preferably above 75% on total composition.

Acrylic polyol resins compositions

The invention relates to a process for the manufacture of &#x3b1;,&#x3b1;-branched carboxylic acids vinyl esters comprising the following steps:

Process for the manufacture of &#x3b1;, &#x3b1;-branched carboxylic acid vinyl esters

The invention relates to compositions of polyether polyol resins (hydroxyfunctional oligo or poly ether) comprising a mixture of &#x3b1;,&#x3b1;-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.

Polyether polyol resins compositions

The invention relates to compositions of hydroxyl functional acrylic resins (acrylic polyols) comprising a mixture of &#x3b1;,&#x3b1;-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.
