Patent number: 6613860Abstract: The present invention provides composition for treating a substrate comprising a homogeneous mixture of: (a) a fluorinated polyether silane of the formula: Rf1—[—Q—SiY3−xR1x]y (I) wherein Rf1 represents a monovalent or divalent polyfluoropolyether group, Q represents an organic divalent linking group, R1 represents a C1-C4 alkyl group, Y represents a hydrolysable group; x is 0 or 1 and y is 1 or 2; (b) an organic or an inorganic acid; (c) water; and (d) an organic solvent. The invention further provides a method of making such a composition and the use thereof to treat substrates to render them oil and water repellent.Type: GrantFiled: October 12, 2000Date of Patent: September 2, 2003Assignee: 3M Innovative Properties CompanyInventors: Rudolf J. Dams, Franceska M. Fieuws, Steven J. Martin, Michael S. Terrazas, Mark J. Pellerite

Patent number: 6593450Abstract: The invention relates to 2,7-substituted-9-substituted fluorenes and 9-substituted fluorene oligomers and polymers. The fluorenes, oligomers and polymers are substituted at the 9-position with two hydrocarbyl moieties which may optionally contain one or more of sulfur, nitrogen, oxygen, phosphorous or silicon heteroatoms; a C5-20 ring structure formed with the 9-carbon on the fluorene ring or a C4-20 ring structure formed with the 9-carbon containing one or more heteroatoms of sulfur, nitrogen or oxygen; or a hydrocarbylidene moiety. In one embodiment, the fluorenes are substituted at the 2- and 7-positions with aryl moieties which may further be substituted with moieties which are capable of crosslinking or chain extension or a trialkylsiloxy moiety. The fluorene polymers and oligomers may be substituted at the 2- and 7′-positions. The monomer units of the fluorene oligomers and polymers are bound to one another at the 2- and 7′-positions.Type: GrantFiled: January 5, 2001Date of Patent: July 15, 2003Assignee: Dow Global Technologies Inc.Inventors: Edmund P. Woo, William R. Shiang, Michael Inbasekaran, Gordon R. Roof
