Abstract
Metal complexes of polyvalent aryloxyethers appropriately substituted with sterically bulky substituents possess enhanced solubility in aliphatic and cycloaliphatic hydrocarbons and/or when employed as catalyst components for the polymerization of ethylene/α-olefin copolymers, produce products having reduced I10/I2 values.
