Method For Immobilizing Superabsorbent Polymer And Products Derived Therefrom

View page
US Patent:
54199557, May 30, 1995
Filed:
Jun 17, 1993
Appl. No.:
8/079694
Inventors:
Kenneth C. Ehrhardt - Charlotte NC
John B. Hopkins - Pineville NC
Joanne C. Maheras - Charlotte NC
David R. McWilliams - Davidson NC
Assignee:
Hoechst Celanese Corporation - Somerville NJ
International Classification:
A61L 1522
A61L 1524
A61L 1528
US Classification:
428283
Abstract:
The present invention provides super absorbent materials in the form of sheets or fibers made from high melting polymers and having super absorbent polymer material dispersed uniformly throughout. The materials are capable of incorporating large amounts of super absorbent polymer and so demonstrate substantially improved absorbency and retention properties. The superabsorbent materials comprise a matrix material polymer selected from the group consisting of cellulose esters, acrylic acid esters, polyvinyl esters and copolymers of same, particles of superabsorbent material distributed throughout the matrix material and a plasticizer mixed into the matrix material.

US Patent:
55073042, Apr 16, 1996
Filed:
Sep 5, 1995
Appl. No.:
8/523427
Inventors:
Joanne C. Maheras - Charlotte NC
John B. Hopkins - Pineville NC
Heribert Tetzlaff - Charlotte NC
Assignee:
Hoechst Celanese Corporation - Somerville NJ
International Classification:
A24D 306
US Classification:
131331
Abstract:
A blend of cellulose acetate and starch acetate used to make fibers, filaments, yarns, fabrics, plastic materials and other uses is disclosed. Additionally, the invention relates to the process of making said blend; cigarette filters made from tow composed of said blend; cigarettes made with filters made from tow of said blend as well as acetate flake and other compositions containing said blend.

US Patent:
53627660, Nov 8, 1994
Filed:
Mar 9, 1993
Appl. No.:
8/028503
Inventors:
John B. Hopkins - Pineville NC
Joanne C. Maheras - Charlotte NC
John B. Morton - Blacksburg VA
Assignee:
Hoechst Celanese Corporation - Somerville NJ
International Classification:
C08J 928
A61L 1522
US Classification:
523105
Abstract:
A method for the manufacture of an absorbent material containing a superabsorbent polymer is disclosed herein. The processing steps include: providing a matrix material in a suitable solvent; mixing particles of a superabsorbent polymer into said solutioned matrix material to form a suspension; homogenizing the suspension; and removing the solvent from the suspension.

US Patent:
54339944, Jul 18, 1995
Filed:
Dec 18, 1992
Appl. No.:
7/994210
Inventors:
Betty J. McKinney - Charlotte NC
Joanne C. Maheras - Charlotte NC
Ronald J. Foltz - Huntersville NC
Steven F. Nielsen - Charlotte NC
Ronald O. Bryant - Charlotte NC
John B. Hopkins - Pineville NC
International Classification:
B32B 700
US Classification:
428246
Abstract:
The instant invention is directed to an article of manufacture for absorbing liquids. This invention comprises: a superabsorbent structure; and a permeable means for coating the superabsorbent structure. The superabsorbent structure comprises a superabsorbent polymer mixed into a matrix material, the matrix material being selected from the group consisting of cellulose ester, acrylic acid ester, polyvinyl ester, copolymers of the foregoing and combinations thereof. The permeable means is laminated onto the superabsorbent structure.
