A thermoplastic polymer comprising a fluorochemical ester composition of formula I:CFSON(Q)(CH)&#x2014;O&#x2014;C(O)&#x2014;(CH)&#x2014;C(O)O(CH)NQSOCF&#x2003;&#x2003;(I)wherein Qand Qwhich may be the same or different are each a hydrogen or an alkyl group of 1 to 4 carbon atoms; a is an integer from 2 to 11; b is an integer from 2 to 11; and n is at least 10.

Fluorochemical diesters as repellent polymer melt additives

This invention describes hydrophobic and oleophobic fibers, films and molded articles comprising synthetic organic polymer wherein dispersed within the fiber, fabric or molded article and present at the surface of the fiber, fabric or molded article are fluorochemical compounds. Method of preparing such fibers, films and molded articles, as well as articles made therefrom also are disclosed.

This invention provides durably hydrophilic, thermoplastic fiber comprising a thermoplastic polymer, such as polyamide, polyurethane, or polyolefin, e.g., polypropylene, and a mixture of: (a) one or more fluoroaliphatic group-containing nonionic surfactants and (b) one or more nonionic, non-fluorinated, polyoxyethylene group-containing surfactants that contain between 20 and 80 weight percent polyoxyethylene. The mixture of the surfactants (a) and (b) is present in the fiber in an amount sufficient to impart durable hydrophilicity to the fiber at its surface. Durably hydrophilic films and durably hydrophilic fabrics and webs constructed from said fibers are also disclosed.

Fluorochemical and hydrocarbon surfactant blends as hydrophilic

A face mask including a face-contacting layer, an outer cover layer, a polymeric microfiber mat disposed between the face-contacting layer and the outer cover layer, and a non-woven fibrous mat disposed between the face-contacting layer and the outer cover layer. The non-woven fibrous mat includes polymeric fibers and a surface energy reducing agent. The face-contacting layer, the cover layer, the polymeric microfiber mat, and the non-woven fibrous mat cooperate with each other to allow gas to pass through the mask while inhibiting the passage of liquid through the mask.

Liquid resistant face mask having surface energy reducing agent on an

Fluorochemical oxazolidinone compositions are provided. They are normally solid, water-insoluble, fluoroaliphatic radical-containing 2-oxazolidinone compounds which have one or more 2-oxazolidinone moieties, at least one of which has a monovalent fluoroaliphatic radical bonded to the 5-position carbon atom thereof by an organic linking group.
