Abstract
A process for the manufacture of glycidylester compositions by (a) reacting: (i) at least one cyclohexyl anhydride compound A; (ii) at least one di-secondary or di-primary hydroxyl compound B containing two (cyclo)aliphatic hydroxyl groups; (iii), at least one di-secondary carboxylic acid or anhydride compound C; and (iv) a mono-glycidyl ester of an α,α-branched carboxylic acid compound D containing from 5 to 19 carbon atoms; and (b) reacting the carboxyl functional polyester from step (a) with an excess epihalohydrin in the presence of a base.
