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.

Sealing compositions for electric cables

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

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.
