US 9,062,163 B2 · High temperature polymer blends of poly(aryl ether ketone phthalazinone)

Abstract

The present invention provides high temperature compositions comprising blends of a first polymer, poly(aryl ether ketone phthalazinone)s, and a second polymer, selected from poly(aryl ether ketone)s, poly(aryl ketone)s, poly(ether ether ketone)s, poly(ether ketone ketone)s, or polybenzimidazoles, thermoplastic polyimides, polyetherimides, poly(aryl ether sulfone)s, poly(phenylene sulfide)s, and mixtures thereof. The compositions have improved high temperature characteristics, e.g., improved high temperature load capability and improved high temperature melt processibility.
