Title:
AMORPHOUS PARTICLES CONTAINING AMIDE ACID OLIGOMER HAVING IMIDO GROUPS, AND PRODUCTION METHOD THEREOF
Document Type and Number:
Japanese Patent JP2022053323
Kind Code:
A
Abstract:
To provide: a production method allowing production of particles containing an amide acid oligomer in a less expensive and more convenient manner in far shorter time than the prior art; and particles containing an amide acid oligomer having novel physical properties and characteristics never found before.SOLUTION: Amorphous particles contain an imido group-containing amide acid oligomer (P) in which some of amide acid units in an amide acid oligomer (A) represented by general formula (2) are converted to imide rings with the imidization rate from 1% to 80% inclusive, where the average particle diameter measured when the particles are dispersed in water is in the range of 100-500 μm.SELECTED DRAWING: None
