Diglycidyl unsaturated ketones of formula ##STR1## e.g., 1,5-bis(p-glycidyloxyphenyl)-1,4-pentadien-3-one, are prepared by condensing one molar equivalent of a ketone of formula R.sup.1 -CH.sub.2 COCH.sub.2 -R.sup.2 with two molar equivalents of an o- or p- glycidyloxybenzaldehyde of formula ##STR2## in the presence of a basic catalyst, where R represents an alkyl or alkoxy group of 1 to 5 carbon atoms, an alkenyl group of 2 to 5 carbon atoms, a carbalkoxy group of 2 to 10 carbon atoms, a cycloalkyl group of 5 to 8 carbon atoms, a halogen atom, a nitro group, or a carboxyl, sulfonic acid, or phosphonic acid group in the form of a salt, m represents zero or 1 to 4, and R.sup.1 and R.sup.2 each represent a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, or together form a straight chain or branched alkylene group of 2 to 6 carbon atoms. The products are useful as photopolymerizable resins.
式为##STR1##的双环氧不饱和酮,例如1,5-双(p-环氧基苯基)-1,4-戊二烯-3-酮,通过在碱性催化剂存在下,将式为R.sup.1-CH.sub.2COCH.sub.2-R.sup.2的酮与式为##STR2##的o-或p-环氧基苯甲醛的两当量进行缩合反应制备而成,其中R代表1至5个碳原子的烷基或烷氧基,2至5个碳原子的烯基,2至10个碳原子的羰基烷氧基,5至8个碳原子的环烷基,卤素原子,硝基,或以盐的形式存在的羧基,磺酸基或膦酸基,m表示零或1至4,而R.sup.1和R.sup.2分别表示氢原子或1至5个碳原子的烷基,或一起形成2至6个碳原子的直链或支链烷基。该产品可用作光聚合树脂。
