“…Алкоголяты щелочных металлов ароматических аминоспиртов нашли применения для получения олигомерных стабилизаторов пролонгированного действия для шинной промышленности [3,4]. Известно, что в качестве катализаторов анионной полимеризации можно использовать металлалкилы, алкоксиды (алкоголяты) и амиды металлов [5][6][7][8][9]. В настоящее время с применением н-бутиллития реализованы промышленные процессы получения полибутадиена марки СКД-Л (ПАО "Нижнекамскнефтехим").…”

At present, the development of modern materials science in the field of development and synthesis of new functional materials for use in various industries is impossible without providing a set of initial compounds of a given composition. Introduction to the composition of organic compounds of metals expanded the synthetic possibilities of organic chemistry. It is known that the catalysts, the polymerization unioneu you can use metallicity, alkoxides (alcoholates), and amides of metals. Currently, with the use of n-butylithium, industrial processes of obtaining SKD-L polybutadiene have been implemented.the Main purpose of this work was to obtain Ethylenediamine-N,N’-sodium diisopropylate and study it as a modifying additive to the initiating system for the production of statistical butadiene-styrene rubber. At the initial stage, it was important to synthesize hydroxypropylated Ethylenediamine, to determine the optimal process conditions, to analyze the composition of products, to establish the optimal ratio of the initial products corresponding to the highest yield of the hydroxypropylated product containing secondary amine groups. The work synthesized alcohol interaction oxypropylation of Ethylenediamine with sodium metal. It was found that the synthesized product exhibits the properties of a modifying additive to the initiating system of styrene-butadiene copolymerization. Butadiene-styrene rubber, obtained on the basis of Ethylenediamine-N, n’-sodium diisopropylate, is strictly statistical and is characterized by an average to a predominant content of 1.2 links in the butadiene part, low content of microblock styrene in the main part of the carbon chain.
