Abstract

An aqueous agent for treating wood and wooden materials, optionally containing customary additives, such as water-soluble wood protecting agents effective as insecticides and/or fungicides, comprises an organic binder drying by oxidation, said organic binder consisting essentially of the reaction product of an acid and a 1,3-butadiene substrate polymer modified to carry amino groups, wherein PA1 (1) the amino group carrying 1,3-butadiene polymer has a double bond content corresponding to an iodine number of at least 200 g iodine/100 g, of which a double bond content of at least 100, measured as iodine number, is derived from cis-1,4-structural elements of the 1,3-butadiene substrate polymer per se; PA1 (2) the amino group content of the amino group carrying 1,3-butadiene polymer is at least 50 mg-atoms of nitrogen/100 g of polymer; and PA1 (3) the 1,3-butadiene substrate polymer per se has at least 70 molar percent butadiene units and a molecular weight (Mn) of 500-6,000.
