US Patent:

6482886, Nov 19, 2002

Filed:

Sep 3, 1998

Appl. No.:

09/077793

Inventors:

Malcolm F. Finlayson - Houston TX
Kenneth E. Springs - Clute TX
John J. Gathers - Pearland TX
James L. Cooper - Lake Jackson TX
Walter L. Vaughn - Conroe TX
Brian H. Schumann - Clute TX

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C08L 302

US Classification:

524562, 524734, 427326

Abstract:

Fibrous product is externally sized by applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid comonomer. The preferred dispersions which have lower initial viscosities provide dispersion/starch dilute solutions with higher viscosities and improved external sizing effectiveness. Resulting fibrous products are adequately sized and exhibit excellent printability and strength properties.

Filed:

May 7, 1976

Appl. No.:

5/684223

Inventors:

Walter L. Vaughn - Lake Jackson TX
James A. Allen - Clute TX

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

D21H 340

US Classification:

162164EP

Abstract:

Cellulosic materials such as paper are internally sized by treating fibers of the cellulosic material, e. g. , paper pulp, with a copolymer of an. alpha. ,. beta. -ethylenically unsaturated hydrophobic monomer and an ammoniated. alpha. ,. beta. -ethylenically unsaturated carboxylic acid and a reaction product of epihalohydrin and alkylamine. Internal sizing of the cellulosic material by this method can be carried out over complete range of pH and is not adversely affected by the presence of contaminants such as alum.

Appl. No.:

5/497781

Inventors:

Walter L. Vaughn - Lake Jackson TX

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

B32B 700

US Classification:

428262

Abstract:

An improved process and composition for water- and oil-proofing textiles which comprises treating a textile with a polymeric fluorocarbon finishing agent and at least one reactive polymer extender of the formula ##EQU1## and curing the treated textile at from 80. degree. C to 170. degree. C for 0. 1 to 60 minutes; wherein C. sub. 1 and C. sub. 2 are carbon atoms of a polyalkylene copolymer chain, R and R' are hydrogen, alkyl, phenyl, --COOH or a segment of a polyalkylene chain, R. sub. 1 and R. sub. 2 are alkyl, aryl, aralkyl, alkaryl, or the like, of up to about 20 carbon atoms, and X is a halogen. The treatment in accordance with the present invention results in synergistic improvements in the oil- and/or water-repellent properties of the conventional fluorocarbon agents.

Appl. No.:

6/776347

Inventors:

Walter L. Vaughn - Lake Jackson TX
Rafael E. Guerra - Lake Jackson TX

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

B01D 1500
C02F 128

US Classification:

210670

Abstract:

Particles, fibers, or filaments of ethylene/carboxylic acid copolymers or terpolymers, especially in highly porous or microporous form, are employed in removing contaminants from solution in aqueous and/or organic liquids, especially metal contaminants. The porous polymers, having a surface area/weight ratio of at least about 0. 5 m. sup. 2 /gm, are useful alone, but may also be used in conjunction with, or in tandem with, previously known ion exchange resins such as polyacrylic acid crosslinked with divinylbenzene.

International Classification:

C02F 142

US Classification:

210687

Abstract:

Hardness values (Ca. sup. ++ and Mg. sup. ++) and other polyvalent metal cations are removed from alkali metal brines (esp. NaCl) by using a high surface area ethylene/carboxylic acid polymer (esp. porous ethylene/acrylic acid copolymers).

C08J 936
B29B 900
B29C 6720

US Classification:

428364

Abstract:

Novel porous fibers and filaments are prepared from normally solid, thermoplastic, orientable, organic polymers which have reactive or reactable groups pendent from the polymer chain, employing a process which involves reactions of said pendent groups while the polymer is in an oriented condition. One of the preferred polymers is a copolymer of ethylene/acrylic acid.
