FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing graft polymers from a polymer based on conjugated diene links and a graft component-thiol derivative and can be used for a bitumen-polymer composition. Method is characterized by absence of solvents and a source of radicals. Derivative of thiol is brought into contact with the polymer at the temperature from 20 °C to 60 °C from 2 to 8 hours, then the mixture is heated at the temperature from 80 °C to 140 °C from 12 to 24 hours.
EFFECT: invention enables reducing viscosity of the obtained bitumen-polymer composition and production of coating materials from it at lower temperatures.
