Abstract: Polyimide compositions containing a lubricious filler and little or no electrically conducting materials are useful for aircraft engine parts, such as bearing, bushings and washers, as well as for other uses. Preferably the polyimides are infusible.

Abstract: The invention relates to a resin blend comprising at least two dry blended, non-melt processible resin particulates, wherein the at least two dry blended, non-melt processible resin particulates are molded by compression molding. The invention also relates to a process for producing a resin blend comprising mixing at least two non-melt processible resin particulates by dry blending and molding the mixture by compression molding. Another aspect of the invention is a resin blend comprising at least two blended, non-melt processible polyimide resin particulates, wherein the at least two blended, non-melt processible resin particulates are molded by compression molding.

Abstract: This invention relates to a polymeric particle, and in particular to a polymeric particle prepared by forming a polyimide in the presence of a particle of base polymer.
