ABSTRACT:
Diepoxides manufactured by epoxidation of diacetals or diketals from .DELTA..sup.3 -cyclohexene-1,1-dimethanol or its homologues and dialdehydes or diketones which apart from the two aldehyde groups or keto groups only contain hydrocarbon radicals, for example the diepoxide of the formula ##SPC1##
The new diepoxides couple good mechanical properties with a significantly higher heat distortion point according to Martens than the known epoxidised diacetals of similar constitution, in which the acetal groups are interrupted by an alkylene-oxyalkylene chain instead of by an alkylene chain which is free of ether oxygen.
