Styrene butadiene rubber categories in terms of production and polymerization methods
Emulsion method In this method, polymerization is done through free radicals, which is done in both hot and cold states. The product obtained by cold method in the presence of oil or in the presence of oil-soot has high linearity, narrow molecular distribution, high molecular mass and difficult processing. The product obtained by hot method is also highly branched and has a wide molecular mass distribution, good process ability and higher percentages of 1 and 2-vinyl. Solution method In this method is ion polymerization, the product of this method has high linearity, high flexibility and high abrasion and tear resistance against dynamic stresses. Gel method The product of this method has a weak percentage of chemical bonds during the polymerization reaction between the chains, which reduces the mobility of the chains and improves processability. cooking methods It is mainly done by sulfur vulcanization method. The cooking speed in the SBR…
Styrene butadiene rubber appearance
Styrene butadiene rubber Origin of styrene butadiene rubber Polybutadiene was one of the first elastomers or tires you had, which is 0% of butadiene production, used to make tires and tires, and 25% to 30% of it is added as an additive to other items than mechanical mechanics. They have to improve. The annual production of this polymer in 2001 is more than 2.1 million tons, which if drugs are used, it is in the second place among tires, after SBR styrene butadiene rubber or styrene butadiene rubber. Polybutadiene was first polymerized in 1910 by a Russian scientist named Sergei Vasilyevich Lebedo Sergei Vasilyevich Lebedev. In 1926 he invented a process for the production of butadiene from ethanol, and in 1928 he was able to use sodium as a catalyst to develop the production of polybutadiene. According to this discovery, the Soviet Union was the first country to succeed in…
