Described herein are novel amino-terminated poly(aryl ether ketone) oligomers and methods for their production. These amino-terminated poly(aryl ether ketone) oligomers are used as building blocks for a variety of polymers and copolymers.

Amino-terminated poly(aryl ether ketones)

Blends comprising from about 1 to about 99 percent by weight of a poly(aryl ether ketone co-carbonate) and from about 99 to about 1 percent by weight of a thermoplastic polymer selected from the group of a poly(aryl ether ketone), a poly(arylene sulfide), a poly(ether imide) or a poly(aryl ether).

Blends comprising poly(aryl ether ketone co-carbonates)

Described herein are random poly(etherimide) containing ether-imide units and aryl ether and/or aryl ether ketone units. These copolymers are produced by the reaction of the appropriate activated dinitro- and/or dihalobenzenoid aromatic compounds with diphenols, and/or by the self condensation of halophenols and/or nitrophenols, whose halogen atom and nitro group are activated towards nucleophilic substitution reactions.

Novel poly (etherimide) compositions

Described herein are novel block copolymers wherein one block is a poly(aryl ether ketone) oligomer and other block is a liquid crystalline polyester oligomer. Processes for the preparation of the subject copolymers are also described. The novel block copolymers display excellent mechanical properties, good high temperatures stability and excellent solvent and chemical resistance.

Novel poly(aryl ether ketone)-polyester block copolymers

Described are novel copolymers of polyphenylene oxides and polyarylates. These copolymers are readily compatible with styrene polymers and copolymers and give tough binary, ternary and quaternary blends.

Copolymers of polyphenylene oxides and polyarylates

Described herein are novel block copolymers wherein one block is a poly(aryl ether ketone) oligomer and the other block is a liquid crystalline polyester oligomer. Processes for the preparation of the subject copolymers are also described. The novel block copolymers display excellent mechanical properties, good high temperatures stability and excellent solvent and chemical resistance.

Novel poly(aryl ether ketone) polyester block copolymers

This invention relates to a novel class of polyetherimides. The subject polyetherimides display a unique combination of high temperature properties, toughness, and melt processability. They are suitable for molding, extrusion, and coating applications. They are also of interest as components of blends, as filled materials, and in composites.
