Zusammenfassung: | This invention pertains to a process for preparing vinyl ester resins containing triazine groups or both triazine and oxazoline groups prepared by reacting a polyepoxide with 0.75 to 1, preferably from 0.9 to 1, moles of a monounsaturated monocarboxylic acid or mixture of monounsaturated monocarboxylic acids per epoxide group in the presence of a suitable quantity of a suitable catalyst. The process is characterized in that the polyepoxide is (a) a polyepoxide containing triazine groups, or (b) a polyepoxide containing both triazine and oxazoline groups, or (c) a mixture of (a) and (b). |
