Abstract: A method for producing a polycondensate powder dispersion, characterised in that it includes at least one step of polycondensation: i) of at least one diester and at least one diamine, and/or ii) at least one amino ester, while stirring, in a solvent that can solubilise both the diamine and the diester and/or the amino ester but not the polyamide that forms during the polycondensation, at a temperature between 30° C. and the boiling temperature of the solvent, in order to produce a powder precipitate dispersed in the solvent.

Abstract: A method for producing a composite material, including an assembly of one or a plurality of synthetic reinforcement fibers, impregnated with at least one thermoplastic polymer having a vitreous transition temperature Tg greater than or equal to 80° C. including: i) a step of impregnating said assembly with a precursor composition in the molten state and including: a) at least one prepolymer P(X)n of said thermoplastic polymer, including a molecular chain P having, at the ends n thereof, identical reactive functions X, said prepolymer having a semiaromatic and/or semi-cycloaliphatic structure, b) at least one chain extender including two identical functions Y, which are reactive with at least one of said functions X; ii) a step of polymerization by mass (poly)addition, in the molten state, of said prepolymer with said chain extender, with said thermoplastic polymer of the thermoplastic matrix being the result of said polymerization by mass polyaddition.
