Polybutadiene [butadiene rubber, BR] is a synthetic rubber. It offers high elasticity, high resistance to wear, good strength even without fillers, and excellent abrasion resistance when filled and vulcanized. "Polybutadiene" is a collective name for homopolymers formed from the polymerization of the monomer 1,3-butadiene.
Solution polymerization is a method of industrial polymerization.In this procedure, a monomer is dissolved in a non-reactive solvent that contains a catalyst or initiator.. The reaction results in a polymer which is also soluble in the chosen solvent.
The Bridgman–Stockbarger method, or Bridgman–Stockbarger technique, is named after physicist Percy Williams Bridgman (1882–1961) and physicist Donald C. Stockbarger (1895–1952). The method includes two similar but distinct techniques primarily used for growing boules (single-crystal ingots), but which can be used for solidifying ...
Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup.
1,3-Butadiene (/ ˌ b juː t ə ˈ d aɪ iː n / ⓘ) [8] is the organic compound with the formula CH 2 =CH-CH=CH 2.It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. [9]
Graft copolymers are a branched copolymer where the components of the side chain are structurally different than that of the main chain. Graft copolymers containing a larger quantity of side chains are capable of wormlike conformation, compact molecular dimension, and notable chain end effects due to their confined and tight fit structures.

Nitrile rubber was developed in 1931 at BASF and Bayer, then part of chemical conglomerate IG Farben.The first commercial production began in Germany in 1935. [2] [3]IG Farben plant under construction approximately 10 kilometres (6.2 mi) from Auschwitz, 1942
A telechelic polymer or oligomer is a prepolymer capable of entering into further polymerization or other reactions through its reactive end-groups. [1] It can be used for example to synthesize block copolymers.
