Patent number: 6855772Abstract: The present invention is directed to polymeric treatment preparations for textiles and other fibrous substrates that impart water and oil repellency to fibers, yarns, textiles, or other fibrous substrates. More particularly, this invention comprises an aqueous solution, emulsion or suspension of (a) a fluorinated polymer that contains reactive groups that can complex with metal atoms that have a formal charge of 2 or greater, and (b) one or more metal atoms that have a formal charge of 2 or greater. The invention is further directed to the process for treating fibrous substrates with textile preparations in one step that provide water/soil repellency that is durable to repeated cleanings and to abrasion. This invention is further directed to the yarns, fibers, fabrics, textiles, webs, finished goods, or nonwovens (encompassed herein under the terms “textiles” and “fibrous substrates”) treated with the textile-reactive water- and soil-resistant preparation of the invention.Type: GrantFiled: October 11, 2002Date of Patent: February 15, 2005Assignee: Nano-Tex, LLCInventors: Matthew L. Linford, David S. Soane, David A. Offord

Publication number: 20040152855Abstract: A composition, comprising, in an appropriate medium, at least one polymer with a highly specific ordered structure is disclosed. These compositions find a specific application in the field of make-up and are capable of being applied to keratinous fibres, in particular to the nails, eyelashes, eyebrows and hair. In particular, these compositions can make it possible to obtain a film which exhibits good resistance to chipping, to impacts, to rubbing movements, to scratches and/or to pressing actions.Type: ApplicationFiled: January 17, 2003Publication date: August 5, 2004Applicant: L'OrealInventor: Nathalie Mougin

Patent number: 6767968Abstract: Block copolymers are prepared by living-type or semi-living type free radical polymerization, with said copolymers having at least one random block comprised of at least one hydrophobic monomer and at least one hydrophilic monomer. The selection of hydrophobic and hydrophilic monomers in the random block is determined by the relative hydrophobicity of the monomers to impart selected solubility or dispersability in water and/or alcohols of the overall block copolymer.Type: GrantFiled: October 3, 2000Date of Patent: July 27, 2004Assignee: Symyx Technologies, Inc.Inventors: Mingjun Liu, Damian Hajduk, Jean M. J. Fréchet, Ezat Khoshdel, Ralph B. Nielsen, Dominique Charmot
