Abstract

Catalytic procedure for the mass (co) polymerization of 1,3-dienes, characterized in that the 1,3-dienes and, if necessary, further monomers, without solvents, are polymerized in the spindle of two or more trees, self-cleaning, with the aid of of mixed organometallic catalysts added directly to the monomers of: a) metal compounds of the fourth to sixth secondary group or the eighth main group of the periodic system and b) organometallic compounds of elements of the first to third group of the periodic system, at temperatures from -20ºC to 150ºC.
