Abstract
Novel epoxidised phenol ethers of formula I ##STR1## are described wherein R.sup.1 denotes C.sub.1 -C.sub.20 alkyl, C.sub.5 -C.sub.9 cycloalkyl or C.sub.7 -C.sub.14 aralkyl, R.sup.2 has one of the meanings of R.sup.1 or is, in addition hydrogen or a radical or formula II ##STR2## R.sup.3 denotes C.sub.1 -C.sub.6 alkyl or halogen, R.sup.4 and R.sup.5 denotes hydrogen or C.sub.1 -C.sub.6 alkyl, R.sup.6 denotes hydrogen or methyl, m is 0, 1 or 2 and n is an integer from 0 to 30, with the proviso that at least two radicals, R.sup.2, must be epoxide groups of formula II. The compounds are especially suitable for encasing electronic components.
