Abstract
Metallic complexes having indenyl ligands can be used as an ingredient of a catalyst system. The catalyst system can be used in polymerizations of ethylenically unsaturated hydrocarbon monomers that include both olefins and polyenes. Embodiments of the catalyst system can provide interpolymers that include polyene mer and from 40 to 75 mole percent ethylene mer, with a plurality of the ethylene mer being randomly distributed. The catalyst system also can be used in solution polymerizations conducted in C5-C12 alkanes, yielding interpolymers that include at least 10 mole percent ethylene mer.
Claims10
An interpolymer comprising polyene mer and from 40 to 75 mole percent ethylene mer, a plurality of said ethylene mer being randomly distributed.
A composition comprising
- a) a solvent system that comprises at least 50% by weight of, or optionally consists of, one or more C5-C10 alkanes and
- b) an interpolymer that comprises polyene mer and at least 10 mole percent ethylene mer, a plurality of said ethylene mer optionally being randomly distributed in said interpolymer.
