METHOD FOR THE PRODUCTION OF POLYDIENES WITH REGULATED MOONEY VISCOSITY

The invention relates to a method for the production of polydienes with regulated Mooney viscosity using catalysts based on rare earth compounds and characterized in that the charged conjugated dienes are polymerized in the presence of 0.000 to 80 wt. % 1,2-dienes, in relation to the sum of the char...

Beschreibung
Zusammenfassung:	The invention relates to a method for the production of polydienes with regulated Mooney viscosity using catalysts based on rare earth compounds and characterized in that the charged conjugated dienes are polymerized in the presence of 0.000 to 80 wt. % 1,2-dienes, in relation to the sum of the charged conjugated dienes and charged 1,2-dienes. The polydienes thus produced can be particularly used in the production of automobile tires.
