Estimating the term…
An object of the invention is to provide thermosetting amic acid microfine particles, thermosetting imide microfine particles and crosslinked imide microfine particles of controlled particle shape and size distribution. The invention provides a production technology which comprises mixing a first solution containing a tetracarboxylic anhydride and a C═C bond-containing acid anhydride with a second solution containing a diamine compound, causing precipitation of thermosetting amic acid microfine particles from the resulting mixture, and further producing thermosetting imide microfine particles and crosslinked imide microfine particles from the thermosetting amic acid microfine particles.
A method of producing thermosetting amic acid microfine particles starting with a tetracarboxylic anhydride, a carbon-carbon double bond-containing acid anhydride and a diamine compound to synthesize a thermosetting amic acid, which comprises
A method of producing thermosetting imide microfine particles starting with a tetracarboxylic anhydride, a carbon-carbon double bond-containing acid anhydride and a diamine compound to synthesize a thermosetting imide, which comprises
A method of producing crosslinked imide microfine particles starting with a tetracarboxylic anhydride, a carbon-carbon double bond-containing acid anhydride and a diamine compound, which comprises
