  • Poly(arylene ether)/polyetherimide blends and methods of making the same
    Patent number: 6166137
    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.

  • Transparent blends of polyetherimide resins
    Patent number: 5852085
    Abstract: Disclosed are transparent blends of a polyetherimide, at least one resin selected from the group consisting of polycarbonate resins, poly(ester-carbonate) resins, and polyarylate resins, and an effective amount of a catalyst to provide transparency to the blends. In addition to being transparent, the blends have good ductility as well as high flexural and tensile properties. The yellowness index of the compositions can be improved with the addition of a phosphite.
