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.

Abstract: A water-soluble polymer having quaternary ammonium groups, is prepared by reacting(a) a low molecular weight alkylating agent with(b) a corresponding polymer carrying tertiary, quaternizable amino groups.

Abstract: The low molecular water-soluble onium-catalyst dissolved in the liquid mixture of epoxy resin and excess epihalohydrin obtained by the reaction in the presence of base of a compound having --OH, --SH, --COOH or .dbd.NH groups with excess 1-halo-2,3-epoxyalkane, is separated therefrom by contacting the liquid mixture, either prior to or after separation therefrom of the precipitated salt produced by the reaction, with at least about 5 parts by weight based on the weight of the catalyst present in the liquid mixture, of an adsorbent containing or capable of absorbing at least 1% by weight of water so strongly that it cannot be removed either by drying over concentrated sulfuric acid or by drying at 110.degree. C. and can only be partially removed by drying at 200.degree. C. under vacuum (about 1 millibar), and then separating the adsorbent with catalyst adsorbed thereon from the liquid mixture.
