Publication number: 20150119577Abstract: A membrane separation process using a highly fluorinated polymer membrane that selectively permeates water of an aqueous ionic liquid solution to provide dry ionic liquid. Preferably the polymer is a polymer that includes polymerized perfluoro-2,2-dimethyl-1,3-dioxole (PDD). The process is also capable of removing small molecular compounds such as organic solvents that can be present in the solution. This membrane separation process is suitable for drying the aqueous ionic liquid byproduct from precipitating solutions of biomass dissolved in ionic liquid, and is thus instrumental to providing usable lignocellulosic products for energy consumption and other industrial uses in an environmentally benign manner.Type: ApplicationFiled: October 29, 2014Publication date: April 30, 2015Applicant: CMS TECHNOLOGIES HOLDINGS, INC.Inventors: Daniel Campos, Andrew Edward Feiring, Sudipto Majumdar, Stuart Nemser

Publication number: 20150025293Abstract: A metal exchanged fluorinated ionomer is a copolymer minimally including repeating units of (i) a polymerized derivative of a perfluorinated cyclic or cyclizable monomer and (ii) a strong acid highly fluorinated vinylether compound in which the acid moiety is exchanged with a cation of a Group 11 metal. Metal exchanged fluorinated ionomers are readily soluble and can be formed into thin, selectively gas permeable membranes by solution deposition methods. These membranes are suitable for separating olefins from gas olefin/paraffin mixtures. Good selectivity and transmembrane flux can be obtained without humidifying the membrane feed gas mixture.Type: ApplicationFiled: July 17, 2014Publication date: January 22, 2015Applicant: CMS TECHNOLOGIES HOLDINGS, INC.Inventors: Andrew Edward Feiring, Jonathan Lazzeri, Sudipto Majumdar

Patent number: 7507522Abstract: The present invention relates to novel unsaturated polycyclic compounds containing two fluoroalcohol substitutents. This invention also relates to homopolymers and copolymers derived from such unsaturated polycyclic compounds. The copolymers are useful for photoimaging compositions and, in particular, photoresist compositions (positive-working and/or negative-working) for imaging in the production of semiconductor devices. The polymers are especially useful in photoresist compositions having high UV transparency (particularly at short wavelengths, e.g., 157 nm) which are useful as base resins in resists and potentially in many other applications.Type: GrantFiled: May 17, 2005Date of Patent: March 24, 2009Assignee: E.
