Epoxide resin mixtures

Claim 1

A storage-stable, thermosetting mixture which comprises: (a) a polyimide containing in the molecule at least two radicals of the general formula ##STR11## wherein d represents a bivalent radical containing a carbon-carbon double bond; (b) 0.05 to 10 moles per equivalent of polyimide of an epoxide compound which contains at least one allyl group selected from the group consisting of (α) glycidyl ethers of the formula ##STR12## (β) glycidyl ethers of novolaks (x) which contain two or more epoxide groups per molecule and are substituted on an aromatic nuclei with at least one allyl group, (γ) polyepoxy adducts (Y), having two or more epoxy groups per molecule, produced by an advancement reaction of one or more diepoxide compounds with one or more bisphenols, where at least one reactant is substituted on an aromatic nuclei with at least one allyl group, (δ) epoxide compounds (Z) produced by the reaction of bisphenols, which are substituted on an aromatic nuclei with at least one allyl group, with epichlorohydrin in alkaline solution; (c) up to 2 moles of a curing agent for epoxide compounds per equivalent of polyimide; and, (d) up to 3 percent by weight, relative to the polyimide, of a curing accelerator for epoxide resins.
