ABSTRACT:
The invention relates to copolyether resins having end groups --OR.sup.1 linked direct to phenyl nuclei and containing 1 to 50 mol % of repeating structural units of formula I ##STR1## and 99 to 50 mol % of repeating structural units of formula II ##STR2## wherein R.sup.1 is hydrogen, a phenylene radical substituted by amino groups or ethylenically unsaturated radicals or is a 2,3-epoxypropyl radical, R.sup.2 is a direct C--C bond or a group of formula --C.sub.r H.sub.2r --, --O--, --S--, --CO-- or --SO.sub.2 --, r is 1 to 20, R.sup.3 is hydrogen or methyl, R.sup.4, R.sup.5 and R.sup.7 are inert substituents, m, n and o are each independently 0, 1 or 2, p is 1 or 2, R.sup.6 is a radical of a bisphenol, X and Y are --SO.sub.2 -- or --CO--.
The compounds can be used in particular in conjunction with unsaturated imides as matrix resins for the preparation of fibrous composite structures.
