Abstract: The review of catalytic systems of production of butadiene rubbers is presented in this article. Use of butadiene rubber in different industries and the output is considered. On the basis of studying of the butadiene rubbers given on export it is established that Russia is considered one of the largest exporters. The leading vendors in Russia and abroad are selected. Because of the low cost, availability and unique properties butadiene rubber is and will remain rubber with the large volume of release and to be used in production of buses, the tempered plastic, paint and varnish products, isolation of electric cables and conveyor tapes. In dependence on types of the used catalysts distinguish several main grades of butadiene rubbers. Considerable attention is paid to the main comparative characteristics of these rubbers, them are: viscosity according to Mooney, contents tsis-1.4-links, the molecular weight and molecular mass distribution. It is analyzed as their change affects properties and a microstructure of rubbers. The catalyst which is used in a classical method of receiving SKD is given in article and characteristics of the butadiene rubber received on this catalyst are presented. For the purpose of improvement of utilization properties of rubbers researches on the choice of catalysts are constantly conducted. Perspective catalytic systems are considered and the characteristics received on different catalytic systems are analyzed. Among perspective in article examples of catalytic systems on the basis of π-allelic complexes of nickel, neodymium, litiyorganichesky and kobaltorganichesky connections are given. In process of development of the new markets of butadiene rubbers it will be necessary to develop new, better grades of polybutadiene, using both the systems of alkyllithium, and Ziegler-Natta's system.
