Abstract: The present invention relates to a method of manufacturing sealing compositions for electric wires, wherein one mixes together a filler (comprised chiefly of an alkaline earth carbonate), a binder component, and possibly additives of the type common in the art.The binder component is a combination of two binders: binder I is a homopolymer of 1,3-butadiene or a copolymer which is essentially obtained from 1,3-butadiene; and binder II is a polymer based on 1,3-butadiene and having laterally extending succinic anhydride groups.The sealing compositions are distinguished by good processibility and high dielectric strength.

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(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;(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(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.

Abstract: An aqueous polybutadiene dispersion is applied as the adhesive intermediary layer in the preparation of polyamide coatings on metal objects by a process of sintering the polyamide powders.The dispersion contains a liquid polybutadiene with a dynamic viscosity from about 70 to 30,000 millipascal seconds and with a configuration of 40 to 95% of cis-1,4-polybutadiene, 0 to 30% of trans-1,4-polybutadiene, 1 to 60% of 1,2-polybutadiene and, referred to the polybutadiene, 0.5 to 10% by weight of an emulsifier.
