US Patent:

43508065, Sep 21, 1982

Filed:

Sep 28, 1981

Appl. No.:

6/306110

Inventors:

Kenneth B. Wagener - Asheville NC

Assignee:

Akzona Incorporated - Asheville NC

International Classification:

C08G 6344
C08G 6944
C08G 7316

US Classification:

528289

Abstract:

Segmented copolyesters/copolyethers in which the soft segment polyethers incorporate a thermally stable heterocyclic unit, e. g. , hydantoin, are found to be useful as biomedical materials since the heterocyclic ring prevents crystallization of the soft segment, and further provides a chemically reactive site for incorporating other moieties to enhance certain properties, e. g. , heparin for increasing the non-thrombogenicity of the biocompatible material.

US Classification:

203 37

Abstract:

A method for removing impurities from caprolactam is disclosed. The method comprises the sequential steps of treating the impure caprolactam with phosphorus pentoxide so that the impurities react therewith to form high boiling species and then distilling the so treated impure lactam to recover substantially pure caprolactam as overhead, with the impurities remaining as bottoms.

Filed:

Dec 20, 1976

Appl. No.:

5/752587

Inventors:

Kenneth B. Wagener - Asheville NC
David A. Johnson - Asheville NC

Assignee:

Akzona Incorporated - Asheville NC

International Classification:

C08L 6702

US Classification:

528301

Abstract:

This invention relates to polyester polyether segmented copolymers wherein the polyether segment contains a certain amount of heterocyclic ring repeat units, for example, the hydantoin ring. These polyester polyether segmented copolymers are useful in the production of fibers, films or other extrusion moldings where elastomeric properties are desirable.

Filed:

May 6, 1983

Appl. No.:

6/492071

Inventors:

Kenneth B. Wagener - Asheville NC

Assignee:

Akzona Incorporated - New York NY

International Classification:

H01B 100

US Classification:

252500

Abstract:

There is disclosed a method for increasing the electrical conductivity of a porous synthetic polymeric material. The method comprises depositing an effective amount of a polyacetylene polymerization catalyst throughout the porous structure, subsequently exposing said material to acetylene under polymerization conditions, for a time sufficient to form polyacetylene within the porous structure, and finally doping the resultant product with a conductivity modifying amount of either an electron donor dopant or an electron acceptor dopant. There is also disclosed an improved electrodialysis process wherein an electrolyte solution is placed between opposite faces of two membranes, the first membrane being an anion exchange membrane and the second membrane being a cation exchange membrane, while being subjected to a primary electric field causing the cations in the electrolyte to pass through the cation exchange membrane and the anions to pass through the anion exchange membrane. The improvement comprises using as the cation and anion exchange membranes electrically conductive membranes on which secondary negative and positive potentials are induced, respectively, the strength of the secondary potential being less than that induced by the primary electric field.

International Classification:

C08L 7700
C08L 9100

US Classification:

260 18N

Abstract:

This invention relates to hydantoin polyamide-poly(oxyethylene) block copolymers which have good thermal stability and an increased hydrophilicity of the polyamide blocks, and which can be used as an additive to polyamides, resulting in improved antistatic properties of the polyamides. The formula for a typical copolymer is: ##STR1## IN WHICH X IS 2 TO 5, Y IS ABOUT 23, AND Z IS 2 TO 3.

Assignee:

Akzona Incorporated - Asheville NC

International Classification:

C08G 6368

US Classification:

528289

Abstract:

The disperse dyeability and moisture absorbency of a fiber and film forming poly(ethylene phthalate) ester is improved by including a hydantoin alcohol, hydantoin diacid, or a diester as a comonomer in the mixture of a phthalic acid or diester thereof and ethylene glycol to produce a random copolyester. The dyed fibers are useful for making various kinds of fabrics and articles made therefrom.
