| titleOfInvention | Process for increasing the molecular weight of polybutadiene or polyisoprene produced in a gas phase polymerization using a polymerization catalyst |
| abstract | "PROCESS TO INCREASE THE MOLECULAR WEIGHT OF POLYBUTADIENE OR POLYISOPRENE PRODUCED IN A GASEOUS POLYMERIZATION, USING A POLYMERIZATION CATALYST A method is provided to increase the molecular weight of polybutadiene with a high content of cis-1,4 and / or polyisoprene, as it is polymerized in a gas phase process, starting from 1,3-butadiene or isoprene, in the presence of a catalyst containing nickel, cobalt, or titanium metal, a method that includes introducing a weak hydrocarbon into said polymerization boiling and high volatility, such as isopentane. |
