摘要： The disclosure relates to a steam stripping process for producing purified polyimides, e.g., polyetherimide homopolymers and polyetherimide copolymers. The process can include contacting an initial polyimide with steam to remove a volatile species from the initial polyimide to produce a purified polyimide. The purified polyimide can have a weight average molecular weight of from 5,000 to 80,000 Daltons. The weight average molecular weight of the purified polyimide can be greater than or equal to 90% of the weight average molecular weight of the initial polyimide. The purified polyimide can have less than 44 ppm of a volatile species, having a molecular weight of less than 250 Daltons. The polyimide can have less than 10 ppm of a metal cation.

摘要： A conductive thermoplastic composition is prepared by a method in which poly (arylene ether) and, optionally, a portion of polyamide are added to a first feed port, polyamide is added to a second feed port, and a concentrate of conductive carbon black in polyamide is added to the second feed port or a third feed port. Whereas preparation of conductive poly(arylene ether)/polyamide compositions has typically required an extruder having at a screw length to diameter ratio of at least 40, the present method allows the use of extruders having a screw length to diameter ratio less than 38 and as low as 20 or lower. The conductive thermoplastic composition prepared by the method exhibits high conductivity and high impact strength, and it is useful for molding articles such as electrostatically-paintable automotive exterior panels.
