  • Patent number: 4851466
    Abstract: Nylon 66 polymer is stabilized against heat and light during its preparation by conducting the polymerization in the presence of certain copper complexes, such as cupric amminohydroxide, and KBr and/or KI. Less metallic copper is formed during polymerization than if copper salts (e.g. copper acetate) are used instead of the copper complexes.

  • Patent number: 3960679
    Abstract: In a process for hydrodimerizing an olefinic nitrile, amide or ester by electrolyzing an aqueous solution of the olefinic compound, alkali metal salt and quaternary ammonium or phosphonium cations, the selectivity with which the hydrodimer is produced is surprisingly high when the solution contains less than about 5% by weight of the olefinic compound and alkali metal cations constituting more than half of the total weight of all cations in the solution and the solution is electrolyzed in contact with a cathode consisting essentially of cadmium.
