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). Also disclosed is a method of making the surface-modified fibrous material. The surface-modified fibrous material may be used as a filtration medium for liquids.Type: GrantFiled: June 30, 1995Date of Patent: April 8, 1997Assignee: Kimberly-Clark CorporationInventors: Gunilla E.

Patent number: 5328760Abstract: The process for forming a microporous polymeric semi-crystalline film, involving the steps of cold compressive extruding a precursor film, preferably in a biaxial fashion, so as to compress the film by a factor of about 2 to 1 to about 10 to 1, stretching the film by about 100 to about 500 percent, preferably in a biaxial fashion, and heat annealing either before, during, or preferably after the stretching step at a temperature up to the alpha transition temperature of the polymer for a time sufficient to maintain the microporous character of the final film.Type: GrantFiled: December 2, 1992Date of Patent: July 12, 1994Assignee: Hoechst Celanese Corp.Inventor: Gunilla E.

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. Cussler, Gunilla E. Gillberg-LaForce, Michael J. Sansone, David K. Schisla
