Abstract: The process involves reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents e) catalysts and optionally f) assistants and/or additives, where the blowing agents (d) used are at least one organic carboxylic acid, preferably an aliphatic monocarboxylic acid, optionally in combination with water and/or a physical blowing agent, and where the catalysts (e) used are polyisocyanurate catalysts, preferably alkali metal or ammonium salts of organic carboxylic acids or tris(dialkylaminoalkyl)-s-hexahydrotriazines.

Abstract: Fibrids are prepared by introducing a solution of a polymer into a liquid precipitation medium while exposing it to shearing forces. A poly(amide-imide) resin solution is admixed with a solvent which is miscible with the resin solvent but which is a non-solvent for the resin itself.
