To provide an interpolymer which can have a relatively higher level of long chain branching while maintaining a relatively narrow molecular weight distribution, i.e., a MWD less than about 6 and which is an olefinic polymer exhibiting processability similar to or better than a LDPE but having physical characteristics similar to those of a metallocene-catalyzed polymer.
A polymerization process comprises contacting one or more olefinic monomers or co-monomers in the presence of at least one high molecular weight catalyst and at least one low molecular weight catalyst in a single reactor, and effectuating the polymerization of the olefinic co-monomers in the reactor to obtain an olefinic polymer. Preferably, both catalysts have the ability to incorporate a substantially similar amount of co-monomers in the olefin polymer.
