Abstract:
A composition comprising a polymer, comprising in polymerized form ethylene and at least one addition polymerizable monomer, prepared by polymerizing ethylene and said at least one addition polymerizable monomer in the presence of a catalyst comprising the following components:a. a metal coordination complex corresponding to the formula: ##STR6## wherein: M is a metal of Group 4 or the Lanthanide Series of the Periodic Table of the Elements;Cp* is a cyclopentadienyl or a substituted cyclopentadienyl group wherein one or more carbons of the cyclopentadienyl group are substituted with a C.sub.1 -C.sub.20 hydrocarbyl radical, C.sub.1 -C.sub.20 halohydrocarbyl radical, C.sub.1 -C.sub.20 hydrocarbyl substituted Group 14 metalloid radical, or halogen radical, or optionally two or more such substituents together form a fused ring system; said Cp* being bound in an .eta..sup.5 bonding mode to M;Z is a moiety comprising boron, or a member of Group 14 of the Periodic Table of the Elements, and optionally sulfur or oxygen, said moiety having up to 20 non-hydrogen atoms, and optionally Cp* and Z together form a fused ring system;X independently each occurrence is an anionic ligand group having up to 30 non-hydrogen atoms;n is 1 or 2 depending on the valence of M; andY is an anionic ligand group bonded to Z and M comprising nitrogen, phosphorus, oxygen or sufur and having up to 20 non-hydrogen atoms, optionally Y and Z together form a fused ring system; andb. an activating cocatalyst,wherein said composition comprising a polymer is an asphalt, bitumen, or adhesive composition.
