摘要： A continuous solution polymerization process is disclosed wherein at least two homogeneous catalyst formulations are employed. A first homogeneous catalyst formulation is employed in a first reactor to produce a first ethylene interpolymer and a second homogeneous catalyst formulation is employed in a second reactor to produce a second ethylene interpolymer. Optionally a third ethylene interpolymer is formed in a third reactor. The resulting ethylene interpolymer products possess desirable properties in a variety of end use applications, for example in film applications. A means for increasing the molecular weight of the first ethylene interpolymer is disclosed and/or a means for increasing the temperature of the first reactor, relative to the third homogeneous catalyst formulation. A means for reducing the (α-olefin/ethylene) weight ratio in the first reactor is disclosed and/or reducing the density of the first ethylene interpolymer, relative to the third homogeneous catalyst formulation.

摘要： This disclosure relates to ethylene interpolymer product having intermediate branching. Intermediate branching was defined as branching that was longer than the branch length due to comonomer and shorter than the entanglement molecular weight (M e ). Intermediately branched ethylene interpolymer products were produced in a continuous solution polymerization process employing an intermediate branching catalyst formulation. Intermediately branched ethylene interpolymer products were characterized by a Non-Comonomer Index Distribution (NCID i ), a melt index from 0.3 to 500 dg/minute, a density from 0.858 to 0.965 g/cm 3 , a polydispersity (M w /M n ) from about 2 to about 25 and a CDBI 50 from about 10% to about 98%. A method based on triple detection cross fractionation chromatography (3D-CFC) was disclosed to measure NCID i .

摘要： This disclosure relates to an improved continuous solution polymerization process wherein production rate is increased. Process solvent, ethylene, optional comonomers, optional hydrogen and a bridged metallocene catalyst formulation are injected into a first reactor to form a first ethylene interpolymer. Optionally, process solvent, ethylene, optional comonomers, optional hydrogen and a bridged metallocene catalyst formulation are injected into a second reactor forming a second ethylene interpolymer. The first and second reactors may be configured in series or parallel modes of operation. Optionally, a third ethylene interpolymer is formed in a third reactor, wherein a homogeneous catalyst formulation or a heterogeneous catalyst formulation is employed. In solution, the first, optional second and optional third ethylene interpolymers are combined, the catalyst is deactivated, the solution is optionally passivated and following a phase separation process an ethylene interpolymer product is recovered.

摘要： This disclosure relates to an improved solution polymerization process wherein the molecular weight of an ethylene interpolymer product can be increased relative to a comparative process; or at constant ethylene interpolymer molecular weight the improved process can be operated at higher polymerization temperature relative to the comparative process. This disclosure also relates to an improved solution polymerization process wherein an ethylene interpolymer product at target density can be produced at a lower [a-olefin/ethylene] weight ratio in the reactor, relative to a comparative process. Process solvent, ethylene, optional comonomers, optional hydrogen and a bridged metallocene catalyst formulation are injected into one or more reactors to form the ethylene interpolymer product. The catalyst is subsequently deactivated, the solution is optionally passivated and following a phase separation process the ethylene interpolymer product is recovered.
