History and production of Butadiene Rubber

Polybutadiene was one of the first elastomers or tires to be invented. 70% of the polybutadiene produced is used to make tires and tires, and 25% to 30% of it is added as an additive to other tires to give them mechanical strength. The annual production of this polymer in 2001 was more than 2.1 million tons, which in terms of tonnage consumption among tires, is second only to Styrene Butadiene SBR or Styrene Butadiene Rubber. Polybutadiene for the first time in the year 1910 Polymerized by a Russian scientist named Sergei Vasilyevich Lebedev, he invented a process for the production of butadiene from ethanol in 1926, and in 1928 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 the industrial production of this polymer in the late 1930s. Germany and the United States were among the countries that contributed a lot to the research and development of polybutadiene production. After World War II in the mid-1950s, major advances in catalysts, especially the production of Ziegler Nata catalysts, led to the production of new and improved types of most polymers, including polybutadiene. To obtain the desired properties, polybutadiene rubber is used in alloy with natural rubber and styrene for the production of SBR and HIPS and acrylonitrile for the production of ABS, in which case it has high abrasion resistance and buoyancy. When added to polybutadiene, it is an anti-oxidant. The most important applications of this product are in the production of tires and rubber parts.


It was one of the first types of elastomers or synthetic rubbers to be invented. Since this polymer is very similar to natural rubber, polyisoprene, using it as an elastomer did not require much thought. This tire is suitable for applications dealing with low temperatures. Dentin car tires are often made of polybutadiene copolymers. Belts, hoses, washers and other car parts are also made of polybutadiene because they are better resistant to low temperatures than other polymers. Many polymers become brittle at low temperatures as a result of a phenomenon called glass transition. Hard rubber, called polystyrene, polybutadiene, or rubber, is a copolymer containing polybutadiene.

Flammability characteristics of Butadiene Rubber

  1. It burns in the flame and continues to burn after the flame is removed.
  2. It has a yellowish-orange streak and cracks a little
  3. Black smoke is accompanied by carbon particles.
  4. It does not drip on the flame

  5. Gives the smell of burnt and unpleasant rubber.

Disadvantages of PBR rubber

  1. Heat resistance
  2. Low delay does not ignite
  3. Low resistance to oil and gasoline
  4. Undesirable process ability
  5. Low resistance to ozone

This rubber has properties similar to NR, isoprene and SBR natural rubber and has the lowest glass conversion temperature (except for silicones) and at low temperatures even up to -60 degrees, it shows good performance and therefore It is mainly used as an alloy with other tires to obtain the desired properties. For example, a mixture of BR and SBR in rubber is a suitable compound used today. BR due to tear and burst resistance and SBR to optimize tire friction.
