METHOD FOR PRODUCING FUNCTIONAL POLYAMIC ACID COMPOSITE PARTICLE AND FUNCTIONAL POLYIMIDE COMPOSITE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polyamic acid composite particle or a polyimide composite particle having a particle diameter regulated to the required one, and also having functionality in an industrial scale.;SOLUTION: When producing the functional polyamic acid by reacting at least a tetracarboxylic acid anhydride with a polyfunctional diamine compound, a carrier is mixed therewith at either step in the process to produce the composite particle of the polyamic acid having the functional group, carried by the carrier.;COPYRIGHT: (C)2007,JPO&INPIT
