It is the greatest happiness is to see your

thought turned into a living operation of such grandeur.

From Sergey Lebedev’s diary

From the second half of the 19th century, the rapidly developing industry faced the need for a new type of raw material – rubber. Rubber was required wherever it was necessary to combine elastic flexibility with reliable strength, where sealing, elasticity, and moisture resistance were needed.

In 1909 Sergey Lebedev proved that a rubber-like polymer can be produced from divinyl, and later, in 1928, together with a group of scientists – A.I. Yakubchik, I.A. Volzhinsky, A.M. Slobodkin and others, won the competition for synthetic rubber production, from that moment the era of the creation of the synthetic rubber industry began.

On January 17, 1931, the Council of Labor and Defense issued a resolution on construction of the first synthetic rubber plants, including the Kazan plant. On November 8, 1931, the first brick was laid in the foundation of the future plant.

The construction of the plant began in difficult economic conditions. Lack of experience, shortage of qualified specialists, low level of education of the workers, difficult conditions of their work and life – all this, of course, could not but affect both the pace and the quality of construction. Construction at that time was predominantly seasonal.

By the end of the 30s, 3 synthetic rubber plants were already operating in the country: Yaroslavl, Voronezh and Efremov plants. Kazan plant became the fourth, designated as “SK-4”. On July 16, 1932, the builders laid the foundations of the 1st and 6th production blocks, the next day laying of rubble stone foundation began on these sites. A sharp turn in the course of construction work occurred at the beginning of 1934. By that time, construction of the main production blocks of the plant was completed.

The need for synthetic rubber was constantly increasing with the industrial development of the country. Therefore, in 1934, the construction of Kazan Plant SK-4 was declared a top priority project. According to the decree of the People’s Commissariat for Heavy Industry of the USSR, signed by Sergo Ordzhonikidze, all building materials and equipment for this facility were to be released on priority basis.

Yaroslavl Synthetic Rubber Plant provided invaluable assistance in training Kazan workers and specialists to master the complex technology. Thus, at the beginning of 1936, a large group of Yaroslavl workers consisting of 160 operators and laboratory staff came to the Kazan plant to exchange experience and train young workers. Kazan engineering and technical workers were trained at similar plants. The workers of the Voronezh and Efremov plants also helped Kazan.

In July 1936, all construction work was mainly completed. In the place where once was an empty lot, now were new workshops, huge tanks and columns, intricate entanglement of pipes.

Kazan Plant SK-4 was launched on November 17, 1936.

Creation of the domestic synthetic rubber industry became the subject of special attention and concern on the part of the Communist Party and the Soviet government. An outstanding party figure, administrator of the industry, S.M. Kirov invested a lot of effort, hard work and energy in this important matter for the country.

On March 20, 1935, the Presidium of the Central Executive Committee of the TASSR issued a decree on perpetuating the memory of S.M. Kirov: “In view of the numerous petitions of the Soviet, party and professional organizations of the TASSR to perpetuate the memory of comrade Sergei Mironovich Kirov, who died at the hands of a class enemy, the Presidium of the Central Executive Committee of the TASSR hereby resolves as follows: to name the Kazan Plant SK-4 after comrade S.M. Kirov.”
