Abstract
A process for preparing polymers and copolymers of 2,3-dimethyl-butadiene-1,3 with other conjugated diolefins, characterized in that the polymerization is carried out in the presence of a hydrocarbon solvent and a catalyst formed by contacting a organometallic compound of the formula: mrn-1x (in which m is a metal of group ii or iii of the mendeleev periodic system, r is a group or aryl, x is a halogen atom and n is the valence of the metal m) with a composed of a metal of group viii of said system.
