Curable mixtures based on maleimides and 1-propenyl-substituted phenols

A curable mixture which consists essentially of

• (a) at least one maleimide of formula I ##STR12## wherein R is an n-valent aliphatic or aromatic radical, and n is the number 1, 2 or 3;
• and
• (b) at least one mono- or polyvalent phenol which contains in the molecule at least one 1-propenyl group in the ortho- or para-position with respect to the hydroxyl group, or an isomeric mixture of mono- or polyvalent phenols which are propenyl-substituted in the ortho- or para-position and of 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;
• said mixture containing for each equivalent of imide group in the maleimide of component (a) from 0.05 to 10 mols of the propenyl-substituted phenol or isomeric mixture of phenols of component (b).
