Abstract (en)
[origin: FR2910900A1] Preparing polymer comprising a polyamide, a copolyamide or copolyesteramide by anionic polymerization solution in a solvent, where the polymerization of the monomer, generators of polymer is carried out in the presence of: a catalyst, an activator, and at least one amide comprising N,N'-bis alkylene amide and a charge or organic mineral density of up to 4.5 cm 3>/g, and the amount of amide added in the reaction is determined specific surface area (SSA), to obtain powder particle having diameter approximately constant, is claimed. Independent claims are included for: (1) polymer powder particle comprising polyamide, copolyamide or copolyesteramide; and (2) a composition of particles comprising at least a compound containing carbon nanotubes, metal particles, pigments, dyes, antioxidants, anti-UV, plasticizers or carbon black.
