Abstract

Polyamides having a crystallite size of 2 to 8 microns are obtained by adding as seed crystals to the polymerizing melt a dispersion obtained by grinding an inert solid in a solvent for the polyamide-forming monomers for at least 24 hours until microcrystalline nuclei capable of being filtered through filter paper are obtained. The polyamides may be prepared from capro-, enantho- or lauroyl lactam, hexamethylene diamine adipate or aminoundecanoic acid. Specified solids are silica, silicates such as talcum, graphite and molybdenum disulphide. The solvent may be water or methanol and may contain a wetting agent, e.g. phenol-ethylene oxide condensates or alkaryl or C12- 18 alkyl sulphonates.
