| titleOfInvention | Catalytic system for production polybutadienes, method for preparation thereof, and a process of producing polybutadienes using the same |
| abstract | FIELD: polymerization catalysts. n SUBSTANCE: proposed catalytic system used for production of polybutadienes is based on at least one conjugated diene monomer; organophosphorus acid salt of one or several rare-earth metals, said salt being suspended in at least one inert aliphatic or alicyclic saturated hydrocarbon solvent; alkylation agent selected from trialkylaluminum and dialkylaluminum hydride, wherein molar ratio of alkylation agent to rare-earth metal salt(s) exceeds 5:1; and hydrogen donor selected from alkylaluminum halides excepting alkylaluminum sesquihalides. Catalytic system is characterized by that concentration of rare-earth metal(s) is at least 0.005 mole/L. Polybutadienes obtained according to invention have polydispersity index below 2.1 and Mooney viscosity ML (1+4) at 100°C below 40. n EFFECT: improved physicochemical characteristics of polybutadienes. n 14 cl, 2 tbl, 7 ex |
