Abstract: Disclosed is a method of treating a polyimide, comprising: providing a polyimide to be treated; and contacting the polyimide to be treated with a fluid to obtain a treated polyimide; wherein the polyimide comprises a first repeat unit derived from pyromellitic dianhydride (PMDA) and a second repeat unit derived from 4,4?-oxodianiline (4,4?-ODA); and wherein the fluid comprises a supercritical fluid, a liquid with a surface tension of 10.0 mN m?1 or less under the conditions of the contacting step, or a mixture thereof. Also disclosed are polyimides obtainable by the methods of the invention, formed polyimide products comprising the polyimides of the invention, and articles comprising the formed polyimide products of the invention.

Abstract: The invention relates to an encapsulated metal particle comprising a core encapsulated in a shell, wherein the core comprises a metallic substance, and wherein the shell comprises a insulating substance. The invention also relates to a polymer composition comprising a plurality of the encapsulated metal particles, a mixture comprising a plurality of encapsulated metal particles and plurality of polymer particles, and the use of the encapsulated metal particle as an additive for increasing the thermal conductivity and/or radio frequency (RF) conductivity of a matrix substance such as an adhesive.

Abstract: An actuatable axial piston valve comprising a gear system to transform linear movement from an actuator to linear movement of the valve piston wherein said gear system comprises racks (2,3) and at least one idler pinion (1).
