FIELD: measurement technology.
SUBSTANCE: invention relates to the modified polymers branching degree determining method. Modified diene polymers branching degree determining method, in which the branching degree after polymerization is increased, includes the modified diene polymers Mooney viscosity (ML 1+4 at 100 °C) determination, treatment with the converting mixture of general formula (I) R¹-S-S-R¹ with the further modified diene polymers formation. Polymers Mooney viscosity (ML 1+4 at 100 °C) is determined before and after treatment with the converting mixture, and the branching degree is determined according to the equation.
EFFECT: invention allows to improve the modified diene polymers branching degree determination, which are used in rubber blends with improved wear parameters.
