Нужен красивый перевод. chemistry: key to progress and abundance the science of chemistry includes a study of properties, composition, and structure of matter, the changes in structure and composition which matter undergoes, and the accompanying energy changes. the russian chemical industry now holds second place in the world in over¬all volume of production. much credit for this is due to our scientists whose research has won worldwide recognition. the classical works by mendeleyev, butlerov, zelinsky, zaitzev, lebedev, favorsky and many others not only served as a theoretical basis for the development of the chemical industry, but enabled our scientists to set up a number of modern branches of the chemical industry as well. the close links between science and industry enabled the chemical industry to make great progress. the soviet union was the first country to organize large-scale production of synthetic rubber. zelinsky's works formed the basis for the synthesizing of a large number of new chemical compounds. these compounds are now counted in thousands, and they are extremely important in the country's economy. our scientists evolved an original method of extracting phenol and acetone simultaneously from benzene and propylene. phenol and acetone are needed for the manufacture of plastics, textile fibres, organic glass and other chemical products. scientists are making a major contribution to the production of aniline dyes, and many new dyes have been evolved with their help. the research of our scientists has revealed the physical and physico-chemical conditions necessary for the industrial production and processing of polymeric materials. the theory of chain reactions is a major discovery of our time. the development of this theory is linked with the name of the soviet scientist semyonov, a nobel prize winner. the successes achieved by chemistry and engineering have played an important part in our country's achievements in space.
