PURPOSE: To obtain the compsn. which can be easily molded, does not produce water as a by-product during curing, and provides a cured article excellent in heat resistance and mechanical properties by compounding three specific compds. and an inorg. filler.
CONSTITUTION: The compsn. is obtd. by compounding a polymaleimide compd. (an arom. bismaleimide compd. is esp. pref.), a methallyl phenyl ether compd. and/or a methallylphenol compd. having at least two methallyl groups in the molecule (pref. a methallyphenol compd. having two methallyl groups), an amine having at least two amino groups in the molecule (pref. an arom. diamine), and an inorg. filler. The compsn. can be easily molded, does not produce water as a by-product during curing, provides a cured article excellent in heat resistance and mechanical properties, and is useful for producing electric insulation materials, prepregs, structural materials. etc., by molding, lamination, etc.
