PRODUCTION OF THERMOSETTING RESIN AND THERMOSETTING COMPOSITION USED THEREFOR

摘要

PURPOSE:To produce a thermosetting resin having excellent thermal characteristics using a solventless thermosetting resin composition having good handling properties and being liquid at ambient temperature. CONSTITUTION:(A) A polymaleimide compound such as bismaleimide is reacted with (B) a polyamino compound such as methylene dianiline and (C) maleimide based compound (e.g. allylmaleimide) having ethylenic unsaturated bond or nadic imide based compound (e.g. alylnadic imide) while heating in the presence of a radical catalyst, using the above-mentioned compound (C) at a weight ratio of 1/ 10 to 10 times based on total weight of the above-mentioned compound (A) and the compound (B) to provide the objective cured resin.
