FIELD: polymer chemistry.
SUBSTANCE: material which can be used in industry as a material for tire treads, interior/exterior trim of vehicles, anti-vibration rubbers, belts, shoes, foam bodies and various industrial products. A polymer based on a conjugated diene is described, characterized by the number of branches (Bn), measured according to SEC measurement of light scattering using a viscosity detector, and amounting to 8 or more, demonstrating a change (ΔT) in the oxidation temperature due to the application of a thermal load of 11.9°C or less, and containing a monomeric aromatic vinyl compound unit. Methods for producing a conjugated diene-based polymer, an oil-filled conjugated diene-based polymer, a rubber composition, and a tire are also described.
EFFECT: providing a polymer based on a conjugated diene, which is characterized by recyclability and heat resistance when obtaining a vulcanizate from it.
