Modified Starches As Extenders For Absorbent Polymers
view source
US Patent:

44839502, Nov 20, 1984
Filed:

Dec 10, 1982
Appl. No.:

6/448675
Inventors:

George F. Fanta - Peoria IL
William M. Doane - Morton IL
Edward I. Stout - Shawnee Mission KS
Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC
International Classification:

C08L 302
C08L 304
US Classification:

524 48
Abstract:

Starch-based superabsorbents are extended by blending with highly modified, low molecular weight starches. The dextrinized starches synergistically interact with the superabsorbents thereby permitting dilution without a commensurate reduction in the water absorbency. While the principal utility of the blends is the absorption of aqueous fluids, when hydrated they yield soft, smooth gels useful as high-quality thickening agents.

Highly Absorbent Graft Copolymers Of Polyhydroxy Polymers, Acrylonitrile, And Acrylic Comonomers

US Patent:

41348630, Jan 16, 1979
Filed:

Dec 6, 1976
Appl. No.:

5/748032
Inventors:

George F. Fanta - Peoria IL
Edward I. Stout - Peoria IL
William M. Doane - Morton IL
Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC
International Classification:

C08L 302
US Classification:

260 174GC
Abstract:

Absorbent compositions comprising graft copolymers of acrylonitrile and starch, or related polyhydroxy polymers, are prepared by improved methods of synthesis. Mixing the acrylonitrile with selected water-soluble acrylic comonomers enables unexpected improvements including reduction of the saponification time, total elimination of the base-saponification step, elimination of the starch gelatinization step, preparation of products which absorb large amounts of aqueous fluids under highly acidic conditions, and preparation of products which absorb over 5000 times their weight of deionized water.

US Patent:

40395863, Aug 2, 1977
Filed:

Aug 30, 1973
Appl. No.:

5/393253
Inventors:

Baruch S. Shasha - Peoria IL
William M. Doane - Morton IL
Edward I. Stout - Peoria IL
Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC
International Classification:

C07C14800
US Classification:

260608
Abstract:

A simple and selective technique for the oxidation of thiols resulted in high yields of the corresponding disulfides. The reaction is tailored so that all byproducts are either volatile or insoluble and the end product recovered easily in essentially pure form. A nonexclusive, irrevocable, royalty-free license in the invention herein described, throughout the world for all purposes of the United States Government, with the power to grant sublicenses for such purposes, is hereby granted to the Government of the United States of America.

Highly Absorbent Polyhydroxy Polymer Graft Copolymers Without Saponification

US Patent:

41949986, Mar 25, 1980
Filed:

Oct 30, 1978
Appl. No.:

5/955828
Inventors:

George F. Fanta - Peoria IL
Edward I. Stout - Waco TX
William M. Doane - Morton IL
Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC
International Classification:

C08L 302
US Classification:

260 174GC
Abstract:

Absorbent compositions comprising graft copolymers of starch are prepared by a simplified method of synthesis. By using a mixture of a nonionic acrylic monomer and an anionic sulfonic acid-substituted acrylic monomer, highly absorbent compositions are prepared without the need for an alkaline saponification step. These compositions are also characterized by their ability to absorb large amounts of aqueous fluids under highly acidic conditions.
