Abstract

PURPOSE: A nitrile-substituted quinazolone polymer which is convertible into cured products having excellent heat stability without forming gas, prepared by reacting a bisoxazinone compound with a diamino compound in a solvent.
CONSTITUTION: The nitrile-substituted quinazolone polymer of the purpose is obtained by reacting a mixture containing a nitrile-containing bisoxazinone compound of formula I, wherein Ar is a group of formula II, III or IV, where X is a bivalent atom or group linking aromatic rings together or a group of formula V, R1 is an organic group which is a nitrile-substituted aromatic ring or a nitrile-containing bisoxazinone compound of formula I and a nitrile-free bisoxazinone compound of formula VI, wherein R2 is a monovalent organic group not substituted with a nitrile group, with a diamino compound of formula VII, wherein R3 is a bivalent organic group.
