PURPOSE: To obtain a thermosetting resin raw material composition, capable of providing cured articles having a high modulus of elasticity and excellent heat resistance, by blending tetracyanobenzene with a specific bisphthalonitrile and curing agent in a specific proportion. n CONSTITUTION: A thermosetting resin raw material composition, obtained by blending (A) tetracyanobenzene with (B) bisphthalonitrile expressed by formula I (R is organic group consisting of conjugated double bond, e.g. a group expressed by formula II, etc.) and (C) a curing agent (preferably m- phenylenediamine, etc.). The component (A) is used in an amount of 1W50pts.wt., preferably 2W30pts.wt. based on 100pts.wt. component (B) and the component (C) is used in an amount of 1W10pts.wt. based on 100pts.wt. total amount of the components (A) and (B). n COPYRIGHT: (C)1988,JPO&Japio |
