Abstract
Linear polyether resins containing 100 to 10 mol % of the repeating structural unit of formula I ##STR1## and 90 to 0 mol % of the repeating structural unit of formula II ##STR2## wherein A is a linear unsubstituted or methyl-substituted alkylene group containing 4 to 100 carbon atoms in the linear alkylene chain, X denotes bridge members as defined in claim 1 and Y is an aromatic radical of a divalent phenol as defined in claim 1, are self-crosslinkable and can be crosslinked by heating to a temperature of not less than 250.degree. C. or by irradiation with energy-rich electromagnetic rays, affording products which are insoluble in organic solvents and which have high glass transition temperatures.
