Abstract
PURPOSE: To provide titled compsn. which is useful for varnish, excels in curing characteristics and produces flame-retardant cured articles, consisting of a specified polyvalent maleimide cpd., a bismaleimide cpd. and a polyhydric phenol.
CONSTITUTION: (a) A polyvalent maleimide cpd. of formula I (wherein n is 0.1 or 2) obtd. by the dehydrating reaction of an amic acid resulting from the reaction of maleic anhydride with a polyamine derived from aniline, and (b) a bismaleimide of formula II (wherein R1 is a bivalent radical having not less than two carbon atoms) such as N,N-4,4'-diphenylmethane bismaleimide, are blended with (c) a polyhydric phenol having at least two phenolic hydroxyl gp. in the molecule derived from phenol, bisphenol A, etc. in such a proportion as to give not less than 10wt% of (a) component per sum of (a) and (b) components, to produce titled compsn.
