Abstract
The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved through the incorporation of imide-extended mono-, bis-, or polymaleimide compounds. These 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.
Claims9
An imide-extended bismaleimide having the structure:
- wherein:
- R and Q are each independently substituted or unsubstituted aliphatic, aromatic, heteroaromatic, or siloxane moieties;
- and
- n is 1 to about 10, with the proviso that the imide-extended bismaleimide is not
A method for producing an imide-extended bismaleimide monomer comprising:
- contacting a dianhydride with a diamine under conditions suitable to form an imide having terminal amino moieties;
- and
- contacting the terminal amino moieties with maleic anhydride under conditions suitable to form a maleimide,
- thereby producing an imide-extended bismaleimide monomer.
