ABSTRACT:
This invention relates to a process for the preparation of particulate, high molecular weight polyamides, to the particulate, high molecular weight polyamides prepared by this process, to the use of these polyamides for the production of moulded bodies, especially by extrusion or blow moulding, and to the articles produced from the polyamides according to the invention. The process is characterized in that polyamides are mixed with concentrates of certain compounds containing phosphorus and worked up into granulates and these granulates are converted into high molecular weight products by solid phase after-condensation.
