  • Aqueous media for the treatment of wood and wooden materials and a process for such treatment
    Patent number: 4496613
    Abstract: Wood and wooden materials are treated with aqueous treatment media. These media contain a water-soluble or water-dispersible, oxidatively drying, organic binder. The latter is a low-molecular weight, optionally modified 1,3-butadiene polymer which carries quaternary ammonium groups. This polymer is obtained by reacting an epoxy-group-containing polymer with a secondary and/or primary aliphatic amine and reacting the amination product with a low-molecular weight monoepoxide, during which process 0.05-0.5 mole of the quaternizable amino groups is quaternized per 100 g of the amination product.The treatment media preferably additionally contain wood preservatives and additives customary in the impregnating and varnishing field.

  • Amino-group bearing, low molecular weight 1,3-butadiene polymer for stabilizing plastics
    Patent number: 4469829
    Abstract: Amino-group bearing, low molecular weight 1,3-butadiene polymers used as stabilizers for molded or unshaped plastics in amounts of 0.01 to 2.0 weight percent referred to the plastic, where the amino-group bearing component is derived from a substituted piperidine having the general formula: ##STR1## where R represents similar or different alkyl groups having 1 to 3 carbon atoms.
