<p>A process for producing polybutadiene or polyisoprene in a gas phase reactor by continuously or intermittently introducing a stream of butadiene or isoprene monomer and optionally an inert gas into a polymerization zone while maintaining the temperature within the polymerization zone below the dew point temperature of the monomer present in said polymerization zone in the presence of a transition metal catalyst and in the presence of inert particulate material.</p> |
