IMIDE-LINKED MALEIMIDE AND POLYMALEIMIDE COMPOUNDS

摘要

PROBLEM TO BE SOLVED: To provide formulations that are not brittle while retaining its high modulus and excellent resistance to thermal degradation.SOLUTION: Imide-extended maleimide compounds are readily prepared by the condensation of appropriate anhydrides with appropriate diamines to give amine terminated compounds. These compounds are then condensed with excess maleic anhydride to yield imide-extended maleimide compounds. The present invention provides a maleimide-functionalized thermoset composition without thermally labile linkages, thereby providing superior thermal stability when used as a toughener.
