  • Method for preparing compositions containing maleimide-amide compounds
    Patent number: 4782133
    Abstract: The invention relates to compositions containing 80-30 weight % of bismaleimide-compounds, 5-60 weight % maleimide-amide compounds and 1-10 weight % maleic anhydride derivative.The invention further relates to the preparation of such compositions and to homogeneous curable compositions comprising bismaleimide/maleimide-amide/maleic anhydride compositions according to the invention. The obtained copolymers show good chemical resistance and a high HDT (heat distorsion temperature).
    Type: Grant
    Filed: May 13, 1987
    Date of Patent: November 1, 1988
    Assignee: DSM Resins B.V.
    Inventors: Adrianus de Koning, Jacobus A. Loontjens, Hubertus A. M. Mostert, Hubertus A. A. Omloo
  • Compositions containing maleimide-amide compounds as well as the preparation and application thereof
    Patent number: 4684706
    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.
