Patent number: 5618622Abstract: A surface-modified fibrous material which includes hydrocarbon polymer fibers having cationic or anionic groups on the surfaces thereof and coated with a polyelectrolyte having a net charge opposite to that of the cationic or anionic groups on the surfaces of the fibers. The hydrocarbon polymer may be, by way of illustration, a polyolefin, such as polyethylene or polypropylene. The cationic or anionic groups may be carboxylic acid, sulfonic acid groups, or quaternary ammonium groups. Examples of polyelectrolytes include chitosan, poly(methacryloxyethyltrimethylammonium bromide), poly(acrylic acid), and poly(styrene sulfonate).

Patent number: 5160627Abstract: A process is provided for modifying the properties of a hydrophobic microporous membrane which includes the steps of first providing a hydrophobic microporous membrane, treating it with a surfactant to render the membrane hydrophilic, wetting the membrane with an aqueous solution of a polyol such as polyvinyl alcohol (PVA) and divinyl sulfone (DVS) or a precursor thereof, washing the membrane with water to displace the polyol/DVA from the exterior of the membrane while retaining it in the pores of the membrane, and crosslinking the polyol/DVS into an aqueous gel to yield a hydrophilic microporous membrane having pores filled with an aqueous polyol/DVS gel, the exterior of the membrane being unobstructed by gel. The modified membranes produced according to the process are useful in carrying out chromatographic separations.Type: GrantFiled: December 27, 1991Date of Patent: November 3, 1992Assignee: Hoechst Celanese CorporationInventors: Edward L.

Patent number: 5049275Abstract: A pore modified microporous membrane is disclosed which is made by the process of incorporating a polymerizable vinyl monomer within the pores of a microporous membrane followed by polymerization to secure the resulting polymer within the pores. The process is particularly suitable for modifying a hydrophobic microporous membrane with a hydrophilic polymer, as occurs for example when polyacrylic acid is secured into the pores of a polypropylene microporous membrane. In further applications of the present invention, the inventive method may be used to produce liquid membrane supports for use with or without active carriers.Type: GrantFiled: June 15, 1990Date of Patent: September 17, 1991Assignee: Hoechst Celanese Corp.Inventors: Gunilla E.

Patent number: 4915855Abstract: A spin finish composition is disclosed which contains an associative thickener which does not affect the initial viscosity of the spin finish composition but which causes a substantial increase in viscosity as water contained therein decreases from its initial level to about 70%, and which effects no substantial change in viscosity of the composition as the water contained therein decreases from 40 to 0%. By virtue of this behavior, a spin finish composition results which can be improved in terms of spreadability on the yarns, package build, spin line coherence, the number of broken filaments and the tackiness of the snow formed on the texturings disks. Additionally, variations in the environment in which spin finish is applied e.g., temperature and humidity, do not substantially affect its performance.Type: GrantFiled: April 13, 1989Date of Patent: April 10, 1990Assignee: Hoechst Celanese Corp.Inventors: Gunilla E. Gillberg-LaForce, Helen A. Kravas
