    Abstract: A supported catalyst for the production of carbon monoxide copolymers is obtained by suspending the support in non-polar aprotic solvent, adding a solution of a Group VIIIB, IB or IIB metal complex with bi- or tri-dentate ligand(s) in a polar aprotic solvent, possibly adding non- polar solvent and working up by filtration. A process for the production of linear alternating copolymers of carbon monoxide (CO) and olefinically unsaturated compounds uses an activator compound and a supported heterogeneous catalyst system, which is obtained by: (a) suspension of the support material in a non-polar aprotic liquid (NPAL), (b) controlled addition of a Group VIIIB, IB or IIB metal chelate complex with bi- or tri- dentate ligand(s) as a solution in a polar aprotic liquid, (c) filtration, optionally followed by washing with NPAL and (d) optionally removing liquid residues with inert gas. Alternatively, the mixture obtained from stage (b) may be mixed with NPAL before performing stages (c) and (d) as above. An Independent claim is also included for carbon monoxide copolymers obtained by this process.

    Abstract: Production of a polyamide from an aminonitrile (AN) and water comprises the combination of steps (1), (2) and (3) or (1), (2), (3) and (4) or (1), (2) and (4) where step (1) involves reacting the AN and water at 100-360 deg C/0.1-35 x 10 Pa; step (2) involves reacting the product of step (1) at 150-400 deg C and a pressure below that in (1) to give a first gas phase and a first liquid and/or solid phase and then separating the phases; step (3) involves reacting the first liquid and/or solid phase with a water-containing gas- or liquid-phase at 150-360 deg C to give a product mixture; and step (4) involves post-condensation of the step (3) product at 200-350 deg C and at a pressure below that in (3) to give a second water- and ammonia-containing gas phase and a second liquid and/or solid phase containing the polyamide. The polyamides prepared using the above combinations of steps are claimed per se. Preferably steps (1) - (4) are effected continuously with recycling of the gas phase obtained in each step to a prior step and with the temperature and pressure in steps (1) and/or (3) such that the gas phase is separated off. Step (1) is such that the conversion of the AN nitrile groups is at least 95 mol.% and a chain extender and/or branching agent may be present. The AN is an 8-13C aminoalkylarylnitrile or an w-aminoalkylnitrile with a 4-12C alkylene group, especially a mixture of (by wt.) 50-99.99% 6-aminocapronitrile; 0.01-50% 4-10C aliphatic- alpha ,w-, 8-12C aromatic- or 5-8C cycloalkane-dicarboxylic acid; 0-50% 4-10C alpha ,w-diamine; 0-50% 2-12C alpha ,w-dinitrile; and 0-50% 5-12C alpha ,w-amino acid or lactam.

    Abstract: A process is disclosed for preparing polyaspartic acid salts by treating polycondensates in an aqueous medium with bases. At least 0.7 equivalents of an alkaline metal and/or alkaline earth metal base per mole of the aspartic acid, aspartic acid imide and/or amide units contained in the polycondensates are used. The bases are added during 30 minutes to 20 hours to an aqueous suspension of the polycondensates of aspartic acid heated up to 40 to 140 DEG C, and the reaction mixture is optionally allowed to continue to react. These alkaline metal and/or alkaline earth metal salts of polyaspartic acids obtained by treating aspartic acid polycondensates in an aqueous medium with more than 1 equivalent of an alkaline metal and/or alkaline earth metal base for reducing the molar mass of polycondensates are used as additives for washing and cleaning agents.
