Catalyst structure for olefin polymerization |
| abstract |
A catalyst system having the following formula is described herein. n n nwherein M is a metal; each X is an atom or group banded to M and may be the same or different; R 1 and R 2 may be the same or each may be different and are substituted or unsubstituted cyclopentadienyl or aromatic groups; R B is a structural bridge between R 1 and R 2 imparting stereorigidity thereto and including at least one heteroatom bonded to M, with each of R 1 and R 2 bonded to the same or different heteroatom of R B which heteroatom is also bonded to M; Z is the coordination number of M and is greater than or equal to 4 and m is the number of bonds between M and heteroatoms of R B . |
