Abstract
The production of diene rubbers polymerized by means of Nd catalysts and having reduced cold flow and low intrinsic odor is effected by the polymerization of diolefines adiabatically at temperatures of -20.degree. to 150.degree. C. in the presence of inert organic solvents and in the presence of metallo-organic mixed catalysts based on neodymium carboxylate, by subsequently depressurizing the reaction mixture obtained in this manner by reducing the pressure, and by treating the reaction mixture thereafter with disulphur dichloride, sulphur dichloride and/or thionyl chloride.
