Epoxy resin mixture for the production of flexible moulded articles

Claim 1

A mixture of compounds of the formula I ##STR14## wherein Alk--represents an alkylene group of 1 to 15 carbon atoms, Ar--represents an unsubstituted or substituted o-, m- or p-phenylene group or a group of the formula ##STR15## wherein the benzene nuclei can be substituted by halogen, alkyl or alkenyl of 1 to 4 or 2 to 4 carbon atoms respectively, and X--represents an alkylene or polyoxyalkylene group of 1 to 15 carbon atoms, a carbonyl, oxygen or sulfonyl bridge, and n in the mixture is in general an integer from 0.3 to 1.5, each Z independently of the other represents hydrogen or the group ##STR16## wherein R represents an alkyl group of 1 to 10 carbon atoms, a cycloalkyl group containing 5 or 6 carbon atoms in the ring, an aralkyl group of 7 to 10 carbon atoms or a phenyl group which is unsubstituted or substituted by halogen and/or lower alkyl groups, and the above groups can also contain a ##STR17## in which R' and R" represent an alkyl group of 1 to 10 carbon atoms, a cycloalkyl group containing 5 or 6 carbon atoms in the ring, an aralkyl group of 7 to 10 carbon atoms or a phenyl group which is unsubstituted or substituted by halogen and/or lower alkyl groups, but 50 to 100% of all the Zs represent the group ##STR18## and the viscosity η of the mixture is not more than 20 Pas.
