Today, synthetic polymers occupy a very important position in the life of all mankind.They are used in various fields of our daily life: from clothes, dishes, toys to aircraft, missiles, vehicles.And one of the most interesting and essential for a number of unique properties is a synthetic rubber.The formula is a natural analogue of the regular structure, while synthetic - irregular.
Producing polymers of this type on an industrial scale began just before World War II in Germany and Russia.Butadiene rubber-sodium "Boone" released in Germany.And in Russia, the first to be produced on an industrial scale polybutadiene.It is produced by the method of anionic polymerization of butadiene liquid developed by Lebedev SV
After the war, due to the lack of a natural product, a synthetic variety, and began to publish in the United States.Since then and to this day the release of a variety of materials, which are based synthetic rubber, as well as all rubber products, refers to the large-scale production.Automotive, aerospace and aviation, engineering, construction, electrical engineering, medicine, shoe industry, consumer goods - none of these industries could not exist without this unique polymer.Such widespread use is due to a complex of unique physical and mechanical properties of various types of rubber and rubber based on them.
synthetic rubber - is an elastomer, for which the inherent elasticity, water resistance and electrical insulation properties.With the use of the curing process polymers of this type are able to be processed into rubber and hard rubber.
All polymeric materials in this class are divided on the scope of the rubbers in the special and general purpose.Synthetic general purpose rubber - is one for which a characteristic pattern of highly technical properties (flexibility, strength, durability, and others.).General purpose rubbers used successfully for a wide range of mass-produced products, mainly for car tires.These include butadiene, butadiene-methylstyrene, isoprene rubber and isobutylene-isoprene copolymer (butyl rubber).
Synthetic rubber Special always has several or one unique feature that provides a high-grade special requirements for product performance in extreme conditions.For example, nitrile known for its high oil and petrol-resistant.Fluorinated - it lovely and gaskets with high thermal stability (200 ° C).Also known polysulfide synthetic rubber, vinylpyridine, urethanes, halogenated isobutylene and others.
Despite this variety of polymeric materials structure and properties, to date, the development continues in this area to be able to meet the ever growing demands of different customers in differentareas.
