Abstract
The invention relates to polyepoxides which are obtainable by reacting compounds of formula I ##STR1## wherein n is 1 or 2, and X, if n is 1, is a group R.sub.3, or, if n is 2, X is a group of the formula ##STR2## each of R.sub.1 and R.sub.3 independently of the other is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, allyl, a halogen atom or C.sub.6 -C.sub.10 aryl and R.sub.2 is allyl, 1-propenyl or 2-propenyl, with compounds containing phenolic OH groups, and subsequently epoxidizing the resultant adducts in the presence of a peracid. Said polyepoxides can be used, together with customary epoxy resin hardeners, for the preparation of cured products, in particular for coating electronic components, or as adhesives.
