Abstract

Procedure for obtaining mercaptan-modified polybutadiene, with a ratio of 1.2 double bonds of 30-60% and viscosity indexes of 0.8 to 1.3 dl/g (toluene media at 25ºC), characterized in that the polybutadiene is reacted in solution with mercaptans of general formulas I and II *** (see formula) where R1, R2 and R3 signify hydrogen or, the same or different, represent a straight or branched chain alkyl moiety, or an aryl moiety and n1 represents numbers 1-4 numbers 1-5.
