40974170, Jun 27, 1978

Filed:

May 2, 1974

Appl. No.:

5/466264

Inventors:

Stephen D. Pastor - Edison NJ
Martin M. Skoultchi - Somerset NJ
Henry R. Hernandez - Somerville NJ

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

H01L 1300
C08F 800
C08F 246

US Classification:

252501

Abstract:

A photocurable electroconductive coating composition adapted to be crosslinked and insolubilized by actinic radiation comprises an acrylic monomer, a photoactivatable free radical polymerization initiator and a salt of a copolymerizable organic compound, wherein at least one of the monomers contains more than one polymerizable ethylenically unsaturated group. The cured coatings are insoluble in aqueous and organic solvents and are conductors of electricity suitable for conductive underlayers of photoconductive imaging elements and as antistatic coatings.

Appl. No.:

5/588398

Inventors:

Stephen D. Pastor - Edison NJ
Martin M. Skoultchi - Somerset NJ
Henry R. Hernandez - Somerville NJ

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

C08F 246

US Classification:

20415923

Abstract:

Actinic radiation curable compositions comprise chemically bonded portions of at least one free radical polymerizable hydroxyalkyl ester of an alpha, beta unsaturated carboxylic acid, at least one non-halogenated cyclic anhydride, at least one epoxide and a halogenated free radical initiator which is activatable by actinic radiation. Upon exposure to actinic radiation, these compositions are cured with very little or no inhibition by atmospheric oxygen.

Filed:

Oct 17, 1977

Appl. No.:

5/842669

Inventors:

Henry R. Hernandez - Somerville NJ
Donald S. Greif - Bound Brook NJ
Albert N. Barna - Plainfield NJ
Douglas S. Thornton - Himsdale MA

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

C08B 3100

US Classification:

536109

Abstract:

Water-insensitive starch fibers having an amylopectin content of about 55 to 100% by weight are prepared by extruding a colloidal starch dispersion in thread-like form into a moving coagulating bath. Water-insoluble additives may be incorporated into the starch dispersion so as to produce a fiber containing the additive in encapsulated form.

Appl. No.:

5/842543

Inventors:

Henry R. Hernandez - Somerville NJ
Donald S. Greif - Bound Brook NJ
Albert N. Barna - Plainfield NJ
Douglas S. Thornton - Himsdale MA

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

D21H 512

US Classification:

162141

Abstract:

A process for the production of paper and paperboard is disclosed wherein water-insensitive starch fibers, produced by extrusion of a starch dispersion into a coagulating solution, are employed to replace all or part of the cellulosic or other pulp conventionally employed. There is also disclosed a method for the incorporation of functional additives into paper during the production thereof; and a method for binding fibers in non-woven webs.

Filed:

May 18, 1987

Appl. No.:

7/050649

Daniel B. Solarek - Bridgewater NJ
Teresa A. Dirscherl - N. Plainfield NJ
Henry R. Hernandez - Bridgewater NJ
Wadym Jarowenko - Green Brook NJ

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

C08B 3102
C08B 3302
C08B 3502

US Classification:

536109

Abstract:

Improved amphoteric starch derivatives containing tertiary amino or quaternary ammonium groups and anionic phosphate groups are disclosed. The derivatives which are defined by a minimum bound phosphorus content, a minimum viscosity and other criteria have use as wet-end additives and provide improved drainage properties in the manufacture of paper.

US Patent:

Filed:

Jul 12, 1976

Appl. No.:

5/704528

Inventors:

Wadym Jarowenko - Plainfield NJ
Henry R. Hernandez - Somerville NJ

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

D21H 328

US Classification:

162175

Abstract:

The use in the manufacture of paper of additives comprising derivatives of starches having particular levels of water fluidity and which contain controlled proportions of cationogenic or cationic substituent groups as well as sulfo-succinate groups. The resulting paper containing the latter additives is characterized by improved retention of pigments and increased strength.

Appl. No.:

7/218380

Inventors:

Walter Maliczyszyn - Somerville NJ
Henry R. Hernandez - Flemington NJ

Assignee:

National Starch and Chemical Corporation - Bridgewater NJ

International Classification:

D21H 138

US Classification:

162135

Abstract:

This invention presents a series of blends of ASA-treated and cationic starches for use as external sizes of paper and paperboard products. The blends contain at least 30% (by wt) of the ASA-treated starch, which is a monoester of the starch and an alkyl or alkenyl succinate and, optionally, from about 0. 5 to about 5% (by weight based on the starch) of an Al. sup. 3+ salt.
