CONTINUOUS SOLUTION POLYMERIZATION PROCESS

This disclosure relates to a continuous solution polymerization process wherein production rate is increased. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst formulation are injected into a first reactor forming a first ethylene interpolymer. Process solvent, ethylene, optional comonomers, optional hydrogen and a heterogeneous 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 an optional third reactor, wherein an optional heterogeneous catalyst formulation may be employed. In a solution phase, the first, second and optional third ethylene interpolymers are combined, the catalyst is deactivated, the solution is passivated and following a phase separation process an ethylene interpolymer product is recovered.
