Abstract
This disclosure relates to a continuous solution three reactor polymerization process. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst system are injected into a first and second reactor configured in parallel to one another. A third reactor receives effluent from the first reactor, the second reactor, or a combination of the first and second reactors. Fresh monomer is feed to the third reactor for further polymerization and to give a final polyethylene product.
