Characteristics of Butadiene Rubber
- It burns in the flame and continues to burn after the flame is removed
- It has an orange-yellow peel and crackles a little
- Black smoke contains carbon particles
- It does not drip in the flame
- It smells of burnt rubber and unpleasant
History and how to produce Butadiene Rubber
Polybutadiene was among the first elastomers or rubbers that were invented, 70% of the produced polybutadiene is used to make rubber and tires, and 25% to 30% of it is added as an additive to other rubbers to increase their mechanical strength. The annual production of this polymer in 1380 was more than 2.1 million tons, which ranks second among tires in terms of consumption tonnage, after Styrene Butadiene Rubber or Styrene Butadiene Rubber. Polybutadiene for the first time in the year 1910 by a Russian scientist named Sergei Vasilievich Lebedev polymerized In 1926, he invented a process for the production of butadiene from ethanol, and in 1928 he was able to develop the production of polybutadiene using sodium as a catalyst. According to this discovery, the Soviet Union was the first country to industrialize this polymer in the late 1930s. Among the countries that contributed a lot to the research and development of polybutadiene production were Germany and America. After the Second World War in the mid-1950s, major advances in the field of catalysts, especially the production of Ziegler Nata catalysts, led to the production of new and improved types of polymers, including polybutadiene. To obtain the desired properties, polybutadiene rubber is used as an alloy with natural rubber and styrene to produce SBR and HIPS, and acrylonitrile to produce ABS, and in this case it has high abrasion resistance and resilience. The most effective additive What is added to polybutadiene is Anti-Oxidant.
