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.

A preparation method of vinyl ester resin for optimizing heat-release during curing includes: (A) providing a vinyl ester, a solvent and a phase change material to perform mixture; (B) performing a heating process to remove the solvent, so as to obtain a vinyl ester resin containing the phase change material. Thereby, the organic PCM material with high heat absorption and good resin affinity can be used as the temperature control agent of the vinyl ester resin during the curing process for avoiding the defects such as bubbles and cracks being generated in the vinyl ester resin.
