摘要：
A gas phase copolymerization of ethylene is disclosed. The process uses a supported single-site catalyst that contains a heteroatomic ligand and produces polyethylene that has a reduced density. Suitable heteroatomic ligands include boraaryl, azaborolinyl, pyridinyl, pyrrolyl, indolyl, carbazolyl and quinolinyl.
