Abstract
Novel polyethylene copolymers having a relatively high comonomer partitioning tendency are disclosed as are methods for their preparation. The comonomer partitioning tendency is the tendency for a copolymer to have comonomer in the higher molecular weight chains. Novel metrics for describing the comonomer partitioning tendency are also disclosed.
Claims12
A method for preparing a polyethylene copolymer having a comonomer partitioning tendency of greater than 1.16 by polymerizing ethylene and one or more comonomers in the presence of one or more catalyst compositions.
