DE 102006016307 A1 UPAB: 20080220 NOVELTY - Matrix microparticle and/or microcapsule with a capsule wall comprises a thermally stable polyimide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for the preparation of thermally stable matrix micro-particles or microcapsules comprising (a) preparing a solution of polyamidocarboxylic acid by the reaction of monomeric diamines and tetra carboxylic acid derivatives, or by dissolving polyamdiocarboxylic acid in a solvent, (b) matrix micro-particle forming and/or micro capsulating the dissolved polyamido carboxylic acid after coagulation or precipitation process, (c) isolating the polyamido carboxylic acid matrix micro particles or capsules, (d) forming polyimide matrix microparticels or capsules of the poylamidocarboxylic acid and (e) separating the polyimide matrix micro particles. USE - The thermally stable matrix micro-particles or microcapsules is useful as fillers and/or additives for thermal and/or mechanical high engineering plastics (claimed). ADVANTAGE - The matrix microparticle and/or microcapsule exhibits high thermal- (claimed), mechanical- (such as tensile strength, bending strength and toughness), light-, chemical- and heat stability.
