CURABLE MIXTURES BASED ON MALEIMIDES AND PROPENYL-SUBSTITUTED PHENOLS, AND THE USE THEREOF

摘要

Curable mixtures of a) maleimides of the general formula I (I) wherein R is an n-valent aliphatic or aromatic radical, nd 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 havlng 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 moulded materials having valuable mechanical properties.
