High Melting Thermoplastic Elastomeric Alpha-Olefin Polymers (Pre/Epe Effect) And Catalysts Therefor
US Patent:
6559262, May 6, 2003
Filed:
Sep 25, 2000
Appl. No.:
09/669411
Inventors:
Robert M. Waymouth - Palo Alto CA
Raisa Kravchenko - Wilmington DE
Larry L. Bendig - Aurora IL
Eric J. Moore - Carol Stream IL
Charles L. Myers - Palatine IL
Roger W. Quan - Vernon Hills IL

Assignee:
The Board of Trustees of the Leland Stanford Jr. University - Stanford CA
International Classification:
C08F21002
US Classification:
526348, 526160
Abstract:
This invention relates generally to low ethylene insertions into I-olefin polymers and processes for production of such polymers using unbridged fluxional metallocenes, primarily substituted aryl indenyl metallocenes, and more particularly to use of unbridged, fluxional, cyclopentadienyl or indenyl metallocene catalyst systems in methods of production of high melting point I-olefin homo- and co-polymers, particularly elastomeric crystalline and amorphous block homo- and co-polymers of I-olefins. The activity of fluxional unbridged metallocene polymerization catalysts containing at least one 2-arylindene ligand is increased 10Ã or more by the addition of small (typically 0. 1-10 wt. %) amounts of ethylene to the polymerization system, which increase is termed the Polymerization Rate-Enhancement effect (PRE), which is measured in terms of an Ethylene Enhancement Factor (EEF) as a dimensionless ratio in the range of from about 1. 1 to about 10 or above. The amount of ethylene included in the reaction system can be selected and controlled to be so small as to result in essentially minimal (2 mole %) incorporation of ethylene units into the resulting elastomeric polymer and the molecular weight may be increased.

International Classification:
C08F004/64
C08F004/68
C08F004/68
US Classification:
502152, 502103, 502117, 526160, 526170, 526943, 556 43, 556 52, 556 53
Abstract:
A metallocene catalyst system component for polymerization of olefins includes at least one 2-arylindenyl ligand substituted on the 1-position by a substituted or unsubstituted alkyl, alkylsilyl, or aryl substituent of 1 to 30 carbon atoms.
