Abstract
The invention relates to compounds of the formula I ##STR1## in which A is a group ##STR2## R.sup.1 is hydrogen or methyl R.sup.2 is C.sub.1 -C.sub.6 -alkyl, halogen or phenyl, PA1 X is a direct C--C bond, --CH.sub.2 -- or --SO.sub.2 --, PA1 m is 0, 1, 2 or 3, n is 0, 1 or 2 and PA1 p is 0 or, in the case of X=--CH.sub.2 --, can also be an integer from 1 to 6, with the proviso that the groups --A and --O--A are in the ortho-position relative to one another. The compounds can preferably be used as matrix resins for composite materials. The invention also relates to the allyl glycidyl ether intermediates, from which the compounds of the formula I are as a rule prepared by epoxidation with peracids.
