Removing Fluorosurfactant From Aqueous Fluoropolymer Dispersions Using Anion Exchange Polymer With Functional Groups Resistant To Degradation To Trialkylamines

US Patent:
7666927, Feb 23, 2010
Filed:
Dec 2, 2005
Appl. No.:
11/292454
Inventors:
James R. Combes - Longmont CO, US
David William Johnson - Washington WV, US
Stephen Thomas Breske - Wilmington DE, US
Assignee:
E.I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C08L 1/00
US Classification:
523310, 523332, 524458, 524482, 524544, 524545
Abstract:
A process for reducing fluorosurfactant content of a stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion comprising contacting the stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion with an anion exchange resin comprising a polymer and quaternary ammonium functional groups to reduce fluorosurfactant content, the functional groups being resistant to degradation which releases trialkylamines. The anion exchange resin is separated from the dispersion after the fluorosurfactant content has been reduced.

Appl. No.:
12/641433
Inventors:
James R. Combes - Longmont CO, US
David William Johnson - Washington WV, US
Stephen Thomas Breske - Wilmington DE, US
Assignee:
E I du Pont de Nemours and Company - Wilmington DE
International Classification:
C08L 1/00
US Classification:
523310, 523332, 524458, 524482, 524544, 524545

Magenta Toner With Binder Resin Of Selected Molecular Weight Composition

US Patent:
8313880, Nov 20, 2012
Filed:
Aug 13, 2009
Appl. No.:
12/540577
Inventors:
Danielle Renee Ashley - Longmont CO, US
James Robert Combes - Boulder CO, US
John Joseph Earley - Boulder CO, US
Lale Gokbudak Lovell - Longmont CO, US
George Pharris Marshall - Denver CO, US
Walter Mychajlowskij - Superior CO, US
Assignee:
Lexmark International, Inc. - Lexington KY
International Classification:
G03G 9/087
US Classification:
4301093, 4301091, 4301114, 4301371
Abstract:
The present disclosure relates to a magenta toner formulation that may be used in a toner printer cartridge for an electrophotographic printer. The magenta toner may include polymer resin binder containing three polymer resins with different number average molecular weight values. The concentration of such polymer resins may be selected to provide a desired temperature versus viscosity behavior for the magenta toner that may be configured to conform to the viscosity versus temperature provide for yellow, cyan and black toner.

Removing Fluorosurfactant From Aqueous Fluoropolymer Dispersions Using Anion Exchange Polymer With Functional Groups Resistant To Degradation To Trialkylamines

US Patent:
8329782, Dec 11, 2012
Filed:
Dec 18, 2009
Appl. No.:
12/641423
Inventors:
James R. Combes - Longmont CO, US

Toner Formulation

US Patent:
2008029, Dec 4, 2008
Filed:
Jun 4, 2007
Appl. No.:
11/757580
Inventors:
Danielle Renee Ashley - Longmont CO, US
James Robert Combes - Boulder CO, US
John Joseph Earley - Boulder CO, US
Lale Gokbudak Lovell - Longmont CO, US
George Pharris Marshall - Denver CO, US
Walter Mychajlowskij - Superior CO, US
Tao Yu - Louisville CO, US
International Classification:
G03G 9/097
G03G 9/00
G03G 9/087
US Classification:
4301084, 4301091, 4301102
Abstract:
The present disclosure relates to a method of forming a toner composition, and to a toner composition, that has a controlled particle size distribution, wherein the particle size distribution may be controlled by adjusting the concentration of a charge control additive in a chemical process of toner manufacture. The toner may therefore have a controlled amount of toner particles having diameters of less than or equal to about 4.0 microns. The toner may therefore provide improved resistance to filming on a given printer component.

Regulated Cooling For Chemically Prepared Toner Manufacture

US Patent:
2009014, Jun 11, 2009
Filed:
Dec 7, 2007
Appl. No.:
11/952355
Inventors:
Danielle Renee Ashley - Longmont CO, US
James Robert Combes - Boulder CO, US
Donna Marie Erk - Louisville CO, US
Lale Gokbudak Lovell - Longmont CO, US
James Michael Piffarerio - Erie CO, US
William Albert Spalding - Longmont CO, US
International Classification:
G03G 9/12
US Classification:
43013714
Abstract:
The present disclosure relates generally to chemically prepared toner (CPT) that employs a regulated cooling process subsequent to coalescence and fusing. The cooling process may influence the distribution of domain morphology of the components within a toner particle such as controlling release agent domain formation and accompanying migration to the toner particle surface.
