Abstract

Abstract Mono- and polyvalent phenolglycidyl ethers which contain in the molecule at least one 1-propenyl group in the ortho- or para-position with respect to the glycidyl ether group, or isomeric mixtures of mono- or polyvalent phenolglycidyl ethers which are propenyl-substituted in the ortho or para-position with respect to the glycidyl ether group and mono- or polyvalent phenolglycidyl ethers which are allyl-substituted in the ortho- or para-position with respect to the glycidyl ether group, the proportion of propenyl groups in the isomeric mixture having to be at least 5 equivalent-%, relative to the sum of the equivalents of propenyl and allyl groups, are obtained by a process wherein the propenyl-substituted phenols, or isomeric mixtures of propenyl- and allyl-substituted phenols, are glycidylated with an epihalohydrin. The novel compounds can be converted, both by use of curing agents for epoxide resins and by radical polymerization, into polymers having valuable mechanical properties.
