Abstract
A dual reactor solution polymerization process gives polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which has a balance of barrier properties, toughness and environmental resistance. The polyethylene compositions are suitable for end use applications which may benefit from low oxygen transmission rates such as closures for bottles or barrier film.
