Abstract: Melt stable polyaryletherketoneketone are prepared from a reactive, lower molecular weight polyaryletherketoneketone having an ultraviolet absorbance at 455 nm of at least 0.185 when measured in 0.1% solution in dichloroacetic acid.

Abstract: Compositions and methods for a melt processable semicrystalline poly(aryl ether ketone) incorporating phthalazinone and 4,4?-biphenol as comonomer units are described herein. The polymers are resistant to and insoluble in common organic solvents and liquids as well as in aggressive organic solvents such as chloroform and chlorinated liquids. The polymers are melt processable via techniques such as extrusion, injection molding, and compression molding. The semicrystalline poly(aryl ether ketone) containing phthalazinone comonomer units have properties which make them suitable for manufacturing high temperature resistant molded systems and other articles.

Abstract: A sealed mat system discharge of a fluid or a solid material comprises interconnected channels, seals, and a composite panel structure.

Abstract: A sealed mat system that protects an environment from discharge of a fluid or a solid material is disclosed as well as a method for deploying the sealed mat system. The sealed mat system for spill containment comprises interconnected channels, seals, and a composite panel structure that secures solid and liquid waste products on the mat system, thereby preventing release of such products into the environment. The leak resistant system is field useable such that it is able to withstand the harsh environments associated with a field job site while also providing a safe working surface for personnel.

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.

Abstract: The present invention is directed to an extrudable resin composition and a method of extruding the extrudable resin composition, comprising a high temperature engineering thermoplastic, one or more reinforcement components, an enhancing filler component, a polymeric lubricant, and an external lubricant, wherein the extrudable resin composition is capable of withstanding temperatures up to about 427° C. The invention is further directed to the use of the extruded pipes and/or lined pipes, produced according to the present method, in downhole tubular applications in oil and gas production; in line pipe, flow line, and transportation line applications in oil and gas production and supply operations; or in most any application where corrosive protection is required to transmit or store corrosive fluids, particularly at high temperatures.
