A polymerization process comprises contacting one or more olefinic comonomers
in
the presence of at least a high molecular weight catalyst and at least a low molecular
weight catalyst in a single reactor, and effectuating the polymerization of the
olefinic comonomers in the reactor to obtain an olefin polymer. Preferably, both
catalysts have the ability to incorporate a substantially similar amount of comonomers
in the olefin polymer. The polymers produced by the process may have a relatively
higher level of long chain branching while maintaining a relatively narrow molecular
weight distribution, i.e., MWD less than about 6. These interpolymers may exhibit
processability similar to or better than LDPE but have physical properties similar
to metallocene catalyzed polymers.
