Catalysts For Olefin Polymerizations

View page
US Patent:
6451940, Sep 17, 2002
Filed:
Oct 13, 2000
Appl. No.:
09/687195
Inventors:
Frederick Hicks - Somerville MA
Maurice S. Brookhart - Chapel Hill NC
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F 460
US Classification:
526161, 5261691, 526171, 526172, 526308, 526281, 526346, 502117, 502155, 502167, 556148, 556150, 568305
Abstract:
Selected nickel complexes of the anions of certain 2-aminotropones are olefin polymerization catalysts. Novel 2-aminotropones and their nickel complexes are also disclosed together with methods of making these 2-aminotropones. Suitable complexes have the following structure: wherein: R is hydrocarbyl or substituted hydrocarbyl, provided that R is attached to said nitrogen atom in (I) by an atom that has at least other atoms that are not hydrogen attached to it; and R , R , R , R and R are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that any two of R , R , R , R and R vicinal to one another may form a ring; L is a monodentate monoanionic ligand and L is a monodentate neutral ligand or an empty coordination site, or L and L taken together are a monoanionic bidentate ligand.

US Patent:
6573353, Jun 3, 2003
Filed:
Sep 12, 2000
Appl. No.:
09/660578
Inventors:
Maurice S. Brookhart - Chapel Hill NC
Lynda Kaye Johnson - Wilmington DE
Christopher Moore Killian - Chapel Hill NC
Elizabeth Forrester McCord - Hockessin DE
Stephan James McLain - Wilmington DE
Daniel Joseph Tempel - Carrboro NC
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08F 1006
US Classification:
526351, 526161, 526172
Abstract:
Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear -olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected -diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected -diimine nickel complexes with ethylene.

Late Transition Metal Diimine Catalyst

US Patent:
6670297, Dec 30, 2003
Filed:
Nov 6, 2000
Appl. No.:
09/707297
Inventors:
Maurice S. Brookhart - Chapel Hill NC
Lynda Kaye Johnson - Wilmington DE
Christopher Moore Killian - Chapel Hill NC
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
University of North Carolina - Chapel Hill NC
International Classification:
B01J 3100
US Classification:
502103, 502117, 502155, 502162, 502167
Abstract:
Catalysts for the polymerization of olefins are provided. The catalysts contain transition metals including nickel and palladium and a diimine ligand in a square planar configuration with two other ligands, and are useful in the polymerization of, for example, olefins, cycloolefins, olefinic esters, and olefinic carboxylic acids. The cocatalyst forms a useable coordinating anion. Polymerization processes using the catalysts can produce homopolymers and copolymers, and the polymers produced may be crosslinked and/or exhibit branching.

US Classification:
502155, 502167, 526161, 526171, 526172, 556 35, 556137, 556138
Abstract:
Certain complexes containing ligands having a phosphino group, amino group or an imino group, and a second functional group such as amide, ester or ketone, when complexed to transition metals, catalyze the (co)polymerization of olefinic compounds such as ethylene, -olefins and/or acrylates. A newly recognized class of ligands for making copolymer containing polar monomers using late transition metal complexes is described.
