PROCESS FOR OBTAINING A CATALYTIC SYSTEM SUITABLE FOR THE POLYMERIZATION OF CONJUGATED DIOLEFINES

A new process is described for polymerising and copolymerising conjugate diolefins, characterised by using a catalytic system formed from at least one metal pertaining to Group III B of the Periodic System, at least one non-halogenated aluminium alkyl, at least one organic halogen derivative or a ha...

More Information
Summary:A new process is described for polymerising and copolymerising conjugate diolefins, characterised by using a catalytic system formed from at least one metal pertaining to Group III B of the Periodic System, at least one non-halogenated aluminium alkyl, at least one organic halogen derivative or a halide of an element also able to exist in a lower valency state, and at least one compound containing one or more salifiable hydroxyl groups, i.e. of acid or neutral type. The new process allows the preparation, both in the absence and in the presence of inert diluents, of conjugate diolefin polymers of linear structure which are essentially entirely 1,4-cis. The method for preparing the new catalytic system is also described.
