, (2008/06/13)
Curable mixtures of (a) maleimides of the general formula I STR1 wherein R is an n-valent aliphatic or aromatic radical, and n is the number 1, 2 or 3; and (b) mono- or polyvalent phenols which contain in the molecule at least one 1-propenyl group in the ortho- or para-position with respect to the hydroxyl group, or isomeric mixtures of mono- or polyvalent phenols which are propenyl-substituted in the ortho- or para-position and mono- or polyvalent phenols which are allyl-substituted in the ortho- or para-position, 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. The novel mixtures cure at elevated temperatures relatively rapidly, and produce molded materials having valuable mechanical properties.
