Abstract: The present invention is directed to a unique poly(arylene ether)/polyetherimide composition having improved impact strength, as well as other improved mechanical and physical properties. This composition comprises: about 40 to about 90 pbw of a polyetherimide resin; about 8 to about 60 pbw of a functionalized poly(arylene ether) resin having a base titratable functionality level of at least 30 .mu.eq/g; and about 0.2 to about 35 pbw of a copolymer of an olefin and an epoxy-functionalized monomer; and may further include catalysts, gloss improvers, stabilizers, and other additives.

Abstract: An ultrasonic measurement device and a method for a non-destructive evaluation of polymer composites having discontinuous fibers distributed therein. The device has one or a plurality of substantially matched pairs of transducers disposed on wedge shaped focuser and a relay, the focuser and relay each have their impedances substantially matched to that of the polymer composite being analyzed. The device is placed on a surface of the composite with the apexes of the focuser and relay in close contact with the surface.
