Abstract
A dual reactor solution process gives high density polyethylene compositions containing a first ethylene polymer and a second ethylene polymer which have a good balance of processability, toughness, and environmental stress crack resistance combined with good organoleptic properties. The polyethylene compositions are suitable for compression molding or injection molding applications and are particularly useful in the manufacture of caps and closures for bottles.
