Abstract:
1. A method of producing a polymer composition comprising incorporating a high molecular weight polymer into a low molecular weight polymer to form the polymer composition in a single polymerization reactor in the presence of polymerizable monomers, a bimetallic catalyst composition and at least one control agent; wherein the control agent is added in an amount sufficient to control the level of incorporation of the high molecular weight polymer, the level of low molecular weight polymer, or both; wherein the control agent is selected from the group consisting of alcohols, ethers, aldehydes, ketones, amines, O wherein the bimetallic catalyst composition comprises a metallocene comprising at least one fluoride ion leaving group; wherein water is also added to the polymerization reactor at from 1 wt ppm to 50 wt ppm, based on the primary monomer feed rate; and wherein from 0.1 to 50 ppm, based on the feed rate of primary monomer in the polymerization reactor, of control agent is added, and the I
