Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures in the presence of a catalyst in the gas phase by a process which comprises carrying out the hydrogenation with a catalyst based on at least one metal selected from the group consisting of nickel, cobalt, ruthenium and rhodium and with the proviso that the catalyst is not a powder.

Abstract: A method for the production of polyamides by polymerization involves being carried out in the presence of water followed by granulation and post-polymerization, in which the monomers are polymerized at a water vapor pressure (p1) of at least 3 bar and the polymer melt is taken off in presence of a liquid, cooled and granulated at a hydraulic pressure (p2) of at least 3 bar. Independent claims are also included for: (1) polyamides obtained by this method; and (2) molded products, film, fibres and foam made from these polyamides.
