PURPOSE: The titled composition useful as electronic parts, etc., having improved workability and setting properties as a material for impregnation, laminating, casting, adhesion, and molding, comprising a polyaminobismaleimide, an unsaturated polyester compound, and a triallyl isocyanurate.
CONSTITUTION: (A) 30W60wt% polyaminobismaleimide obtained by heating 1mol N,N'-bismaleimide(e.g., N,N'-ethylenedimaleimide, etc.) shown by the formula (R is bifunctional organic group such as alkylene group, arylene group, aralkylene, etc. and <1mol(preferably 0.2W0.6mol)diamine such as aliphatic diamine (e.g., ethylene diamine)in triallyl isocyanurate is blended with (B) 10W30wt% unsaturated polyester obtained by condensing a dibasic acid component (e.g., terephthalic acid, etc.) with a diol component(e.g., ethylene glycol, etc.), and (C) 10W50wt% triallyl isocyanurate, to give the desired composition. For example, it is heated at 150W180°C for 3W10min and cured.
