AMIDE-IMIDE COPOLYMER RESIN OF LOW WATER ABSORPTION AND COMPOSITE MADE THEREFROM |
摘要 |
Polyamide-imide matrix resins derived from trimellitic acid compounds and an aromatic diamine are improved in moisture resistance when from 10 to about 90 mole % of the trimellitic acid compounds are replaced by biphenyl tetracarboxylic acid compounds. The matrix resins are particularly useful for fiber-filled composites having improved retention of properties when exposed to moisture. |
