    Abstract: THERE IS DISCLOSED AND CLAIMED A PROCESS FOR THE PRODUCTION OF SHAPED ARTICLES FROM POLYAMIDES WHICH EXHIBIT MELTING RANGES NEAR TO OR ABOVE DECOMPOSTION TEMPERATURES OR POOR OR NO SOLUBILITY AT ALL IN SOLVENTS OR WHICH XHIBIT BOTH OF THESE PROPERTIES AT THE SAME TIME, THE PROCESS WHICH COMPRISES MOULDING POLYAMIDES CARRYING SUBSTITUENTS OF THE AMIDE NITROGEN AND THUS HAVING REDUCED MELTING RANGES AND/OR IMPROVED SOLUBILITY IN SOLVENTS, AND SEPARATING (SPLITTING-OFF) SAID SUBSTITUENTS PARTIALLY PR TOTALLY DURING AND/OR AFTER MOULDING.

    Abstract: THERE IS DISCLOSED AND CLAIMED A PROCESS FOR THE PRODUCTION OF CELLULAR PLASTICS FROM POLYAMIDES, WHICH EXHIBIT MELTING RANGES NEAR TO OR ABOVE THEIR DECOMPOSITION TEMPERATURES OR POOR OR NO SOLUBILITY AT ALL IN SOLVENTS OR WHICH EXHIBIT BOTH OF THESE PROPERTIES AT THE SAME TIME, THE PROCESS WHICH COMPRISES PROCESSING POLYAMIDES CARRYING SUBSTITUENTS AT THE AMIDE NITROGEN, FROM THE MELT OR FROM THE SOLUTION AND SPLITTING-OFF PARTIALLY OR TOTALLY THE N-SUBSTITUENTS TO YIELD CELLULAR PLASTICS BY THE FOAMING ACTION OF THE UNSATURATED COMPOUNDS WHICH ORIGINATE FROM THE N-SUBSTITUENTS DURING THE SPLITTING-OFF PROCESS. THIS FOAMING ACTION IS AUGMENTED BY ADDITIONALLY USING FOAMING OR EXPANDING AGENTS AND/OR REDUCING THE PRESSURE DURING THE SPLITTING-OFF PROCESS.
