Abstract:
The invention relates to compositions of α,α-branched alkane carboxylic acids glycidyl esters with a defined isomeric composition where 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%.The mixture of neononanoic acid glycidyl esters comprising at least 2,2-dimethyl heptanoic acid glycidyl ester and 2-methyl 2-ethyl hexanoic acid glycidyl ester and 2-methyl 2-ethyl 3-methyl pentanoic acid glycidyl esters.
Abstract:
The invention relates to a process for the manufacture of α,α-branched carboxylic acids vinyl esters comprising the following steps: isomerising and converting an olefin feed with CO and water under Koch reaction conditions to make an acid with a ratio of Non Blocking isomers (NB) versus Blocking isomers (B) of NB/B above 1.5, wherein a blocking isomer has always a tertiary carbon atom in alpha position of the carboxylic acid and in the beta position of the carboxylic acid, whereas a non-blocking isomer has primary carbon atoms in the beta position of the carboxylic acid converting the resulting acid into a vinyl ester.

Abstract:
This invention relates to a Waterborne Polyurethane Dispersions (WPU) derived from the reaction products of tertiary alkyl glycidyl esters based hydroxyl terminal polyester polyols with polyisocyanates and chain extended with poly-functional amines and dispersed in water have shown the surprising inherent ability for self-coalescence. Furthermore the cured films have shown improved hardness and abrasion resistance over these benchmarks with a significant reduction in coalescing solvent needed to accomplish film formation.
