FIELD: chemistry.
SUBSTANCE: invention relates to functionalised diene caoutchoucs, their obtaining, to rubber mixtures, containing the functionalised diene caoutchoucs, to the application for manufacturing highly-filled rubber moulded products, especially tyres. The functionalised diene caoutchouc is obtained by the polymerisation of dienes and vinylaromatic monomers and conversion with hydroxymercaptanes in a solvent in an amount of 0.1-5.0 g of hydroxymercaptane per 100 g of the diene caoutchouc. Conversion is carried out in the process of polymerisation.
EFFECT: tyres from the rubber mixture by the invention possess especially low rolling resistance, as well as especially high stability when moving on a wet road and wear resistance.
