Patent number: 6653407Abstract: The present invention is directed to a process for forming star shaped microgels which include a core of crosslinked polymer and multiplicity of substantially linear polymeric arms of macromonomers attached to the core. The process includes polymerizing monoethylenically unsaturated monomers in the presence of a chain transfer agent to form macromonomers each having a terminal polymerizable ethylenically unsaturated group and then polymerizing, in presence of the macromonomers, the monoethylenically unsaturated monomers and multi-olefinic crosslinking monomers. The microgels of the present invention can be used as rheology control agents in waterborne and solvent-borne coatings and in adhesives and cosmetics.Type: GrantFiled: October 3, 2001Date of Patent: November 25, 2003Assignees: E.

Publication number: 20030211417Abstract: Nitrile/vinyl ether-containing polymers for photoresist compositions and microlithography methods employing the photoresist compositions are described. These photoresist compositions comprise 1) at least one ethylenically unsaturated compound comprised of a vinyl ether and 2) a nitrile-containing compound, e.g., acrylonitrile, which together impart high ultraviolet (UV) transparency and developability in basic media. In some embodiments, these photoresist compositions further comprise a fluoroalcohol group. The photoresist compositions of this invention have, high UV transparency, particularly at short wavelengths, e.g., 157 nm and 193 nm, which property makes them useful for lithography at these short wavelengths.Type: ApplicationFiled: October 16, 2002Publication date: November 13, 2003Inventors: Michael Fryd, Periyasamy Mookkan, Frank Leonard Schadt III

Patent number: 6646070Abstract: This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier. The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved.Type: GrantFiled: April 9, 2001Date of Patent: November 11, 2003Assignee: E. I. du Pont de Nemours and CompanyInventors: Charles T. Berge, Michael Fryd, Josef Huybrechts, Kenneth S. Kirshenbaum, Karyn B. Visscher
