ABSTRACT:
Imide prepolymer compositions containing an unsaturated component (A) and diamine component (B) at the (A)/(B) molar ratio of 0.9-1.5 and 0.01-5.0% by weight, based on the sum of said components (A) and (B), of at least one radical polymerization inhibitors, and preferably further 0.01-5.0% by weight, based on the sum of said components (A) and (B), of at least one compound selected from the group of carboxylic acid and carboxylic acid anhydride.
The imide prepolymer compositions of the present invention which contain the above-defined components in specific proportions are tough and excellent in adhesive strength to glass cloths and metals and in heat resistance.
