    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.
