Abstract
A family of novel hetrocyclic-amide type catalyst precursors useful for the polymerization of olefins, such as ethylene, higher alpha-olefins, dienes, and mixtures thereof.
Claims26
A catalyst precursor represented by one of the formula selected from:
- 27
- where a is an integer from 1 to 5;
- T is a chemical moiety having 1 to 100 atoms, which can include hydrogen when a is equal to 1 is a bridging group when a is equal to 2 to 5;
- M is a metallic element selected from Groups 1 to 15, and the Lanthamide series of the Periodic Table of the Elements;
- Z is a coordination ligand;
- m is an integer from 1 to 3;
- each L is a monovalent, bivalent, or trivalent anionic ligand;
- n is an integer from 1 to 6;
- m is an integer from 0 to 5;
- Y is a heteroatom selected from nitrogen, oxygen, sulfur, and phosphorus;
- J is a heteroatom that is part of a ring structure and is selected from nitrogen, oxygen, sulfur, and phosphorus;
- R can be independently hydrogen, or a non-bulky or a bulky substituent;
- and
- b is an integer from 0 to 20.
