GLYCIDYL ESTERS OF ALPHA, ALPHA BRANCHED NEONONANOIC ACIDS, SYNTHESIS AND USES

摘要

The invention relates to a manufacturing process for the preparation ofα,α-branched alkane carboxylic acids providing glycidyl esters with an improved softness or hardness of the coatings derived thereof. In which the mixture of neononanoic acid providing a high hardness is a mixture 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%. In which a mixture of neononanoic acids providing soft polymers is a mixture where the concentration of blocked and highly branched isomers is maximum 55%, preferably below 40% and most preferably below 30%.
