Inventors:
Craig Jon Hawker - Los Gatos CA
Gerrit Klaerner - San Jose CA
Jeong-Ik Lee - Suwon, KR
Victor Yee-Way Lee - San Jose CA
Robert Dennis Miller - San Jose CA
John Campbell Scott - Los Gatos CA
Assignee:
International Business Machines Corporation - Armonk NY
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
C08F11206
US Classification:
5263471, 526171, 526204, 526217, 526260, 526261, 526270, 526287, 526293, 526310, 526347
Abstract:
Multifunctional electroactive copolymers are provided. The copolymers may be A-B-A triblock copolymers, brush-type graft copolymers, or variations thereof. In a preferred embodiment, the copolymers are âdual useâ in that they comprise both a light emitting segment and a charge transport segment. Methods of synthesizing the novel electroactive copolymers are provided as well, as are opto-electronic devices, particularly LEDs, fabricated with the novel copolymers.

Controlled Stable Free Radical Emulsion Polymerization Processes

View page
US Patent:
6472486, Oct 29, 2002
Filed:
Jul 2, 1999
Appl. No.:
09/347609
Inventors:
Gerrit Klaerner - Campbell CA
Adam Safir - Oakland CA
Ralph B. Nielsen - San Jose CA
Bernd Jandeleit - Palo Alto CA
Peter Huefner - San Jose CA
Assignee:
Symyx Technologies, Inc. - Santa Clara CA
International Classification:
C08F 222
US Classification:
526220, 526193, 526201, 526217, 526227, 526922
Abstract:
Controlled stable free radical emulsion polymerization processes employ nitroxide control agents having an alpha carbon atom bearing a destabilizing substituent such as hydrogen. The emulsion polymerizations have living characteristics, including the re-initiation of polymer chains, and provide a high degree of control over molecular weight, particle size, polydispersity and polymer composition and architecture. The processes are useful for the preparation of polymer emulsions, including block copolymers, star and graft copolymers, telechelics and macromonomers from a wide range of monomers.

Controlled Free Radical Emulsion And Water-Based Polymerizations And Seeded Methodologies

View page
US Patent:
6559255, May 6, 2003
Filed:
Mar 8, 2000
Appl. No.:
09/520583
Inventors:
Gerrit Klaerner - Campbell CA
Adam Safir - Oakland CA
Ralph B. Nielsen - San Jose CA
Bernd Jandeleit - Palo Alto CA
Peter Huefner - San Jose CA
Yunxiao Li - Sunnyvale CA
Assignee:
Symyx Technologies Inc. - Santa Clara CA
International Classification:
C08F 222
US Classification:
526220, 526 75, 526 88, 526201, 526217, 526236
Abstract:
Nitroxides having an alpha-carbon atom with a destabilizing moiety are effective control agents for emulsion and water-based polymerizations, including the formation of block copolymers from a wide range of monomers. The nitroxide radicals may be used as a free radical or as an adduct with a residue from the initiator. The emulsions have living characteristics, including the re-initiation of polymer chains. Also, a seeded process for emulsions, which includes the step-wise addition of monomer is disclosed, providing access to a wide range of initiator types.

Polymer Brushes For Immobilizing Molecules To A Surface Or Substrate, Where The Polymers Have Water-Soluble Or Water-Dispersible Segments And Probes Bonded Thereto

View page
US Patent:
6692914, Feb 17, 2004
Filed:
Jul 3, 2000
Appl. No.:
09/609461
Inventors:
Gerrit Klaerner - Campbell CA
Ralph B. Nielsen - San Jose CA
Paul Mansky - San Francisco CA
Didier Benoit - San Jose CA
Dominique Charmot - Los Gatos CA
Bernd Jandeleit - Sunnyvale CA
Laura T. Mazzola - Redwood City CA
Assignee:
Symyx Technologies, Inc. - Santa Clara CA
International Classification:
C12Q 168
US Classification:
435 6, 435 71, 435 72, 536 221, 536 231
Abstract:
Sensors for determining the presence and concentration of bio-molecules in a biological sample are provided in the form of polymer brushes, which comprise a substrate having a surface that is modified with a water-dispersible or water-soluble polymer segment having functional groups that bind probes. The method of synthesis of such sensors preferably includes use of controlled free radical polymerization techniques, which allows for controlled architecture polymers to modify the surface of the substrate. In this manner functional groups in the polymer chain are removed from the surface, which allows for solution chemistry to be more realistically reproduced with the benefits of a solid bound probe.

Controlled-Architecture Polymers And Use Thereof As Separation Media

View page
US Patent:
6716948, Apr 6, 2004
Filed:
Jul 31, 2000
Appl. No.:
09/630328
Inventors:
Gerrit Klaerner - Campbell CA
Miroslav Petro - San Jose CA
Dominique Charmot - Los Gatos CA
Didier Benoit - San Jose CA
Assignee:
Symyx Technologies, Inc. - Santa Clara CA
International Classification:
C08F12054
US Classification:
5263031, 526209, 526210, 526217, 526222, 526236, 524555
Abstract:
Controlled architecture polymers made preferably with acrylamide type monomers are prepared in living-type or semi-living-type free radical polymerizations, with the architecture preferably being other than linear, such as star, branched, grafted or hyper-branched. The controlled architecture polymers have high weight average molecular weights and low viscosities, which make they particularly useful in replaceable capillary electrophoresis separation media for biological molecules, such as DNA fragments.

International Classification:
G01N 33545
US Classification:
436532, 436531, 436527, 436546, 435 6, 530408, 530409, 5303911
Abstract:
Sensors for determining the presence and concentration of bio-molecules in a biological sample are provided in the form of polymer brushes, which comprise a substrate having a surface that is modified with a water-dispersible or water-soluble polymer segment having functional groups that bind probes. The method of synthesis of such sensors preferably includes use of controlled free radical polymerization techniques, and in particular the use of an iniferter initiator, which allows for controlled architecture polymers to modify the surface of the substrate. In this manner functional groups in the polymer chain are removed from the surface, which allows for solution chemistry to be more realistically reproduced with the benefits of a solid bound probe.
