ABSTRACT:
A method for preparing vinyl ester resins comprises reacting mono-, di- or polyhydroxy functional phenols with a tertiary alkyl glycidyl ether in the presence of a catalyst, e.g., triphenyl phosphine, followed by dealkylating and esterifying the adduct with an olefinically unsaturated aliphatic acid, e.g., acrylic acid, in the presence of a strong acidic catalyst, e.g., p-toluene sulfonic acid.
