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).
本发明涉及一种制备含有三嗪基团或同时含有三嗪和噁唑啉基团的乙烯基酯树脂的工艺,其制备方法是在适量的合适催化剂存在下,将聚环氧化物与每环氧基团0.75至1摩尔,最好是0.9至1摩尔的单不饱和单羧酸或单不饱和单羧酸混合物反应。该工艺的特征在于,聚环氧化物是(a)含有三嗪基团的聚环氧化物,或(b)含有三嗪和噁唑啉基团的聚环氧化物,或(c)(a)和(b)的混合物。
