Abstract
A process for the manufacture of linear, substantially gel free, high cis 1,4 poly(butadiene) comprising polymerization in the presence of (a) a catalyst comprising at least one cobalt compound, at least one organoaluminium compound, and water, and (b) a cycloalkane as main solvent component, and (c) at least one substituted benzene as polymerization regulator of the general formula ##STR1## wherein n is an integer in the range of from 3 to 5, and wherein each R represents a lower alkoxy group containing from 1 to 6 carbon atoms.

A process for the manufacture of linear, substantially gel free, high cis 1,4-poly(butadiene) comprising polymerization of 1,3-butadiene in an organic solvent in the presence of (a) a catalyst comprising at least one cobalt compound, at least one organoaluminum compound, and water, and (b) a cycloalkane as the main solvent component, and (c) at least one substituted benzene polymerization regulator of the general formula ##STR3## wherein n is an integer in the range of from 3 to 5, and wherein each R represents a lower alkoxy group containing from 1 to 6 carbon atoms.
