ABSTRACT:
The invention relates to compositions containing 80-30 wt.-% of bismaleimide-compounds, 5-60 wt.-% maleimide-amide compounds and 1-10 wt.-% of a maleic an hydride derivative. The invention also relates to the preparation of such compositions as well as the homogeneous curable compositions, in a suitable solvent, comprising bismaleimide/maleimide-amide/maleic an hydride. The obtained copolymers show good chemical resistance and a high heat distortion temperature.
