Patent number: 7226957Abstract: A method for producing polymers with controlled molecular weight and desired end functionalities and the resulting polymers. The method comprises a) forming a microemulsion comprising monomer, water, and an effective amount of an effective surfactant, b) adding to the microemulsion an amount of a water-soluble photo-initiator system wherein the initiator system produces one type of monomer-soluble radical active centers and wherein the radical active centers contain desired end group functionalities for a polymer or oligomer, and c) illuminating the microemulsion to photoinitiate polymerization of the monomer wherein the illuminating is according to a temporal and spatial illumination scheme, and wherein the amount of the initiator system and the temporal illumination scheme are chosen to produce a desired molecular weight of the polymer or oligomer. The microemulsion can further comprise an effective amount of an effective co-surfactant. The method can be used to produce polymers and copolymers.Type: GrantFiled: November 3, 2003Date of Patent: June 5, 2007Assignee: University of Iowa Research FoundationInventors: Alec Scranton, Kaveri Jain

Patent number: 7112617Abstract: A gas phase species (such as ozone, H2O2, or N2O) is photodissociated with ultraviolet light into a reactive species that is patternwise directed (e.g., through a mask) onto a surface of a material, such as an organosilicate. The reactive species reacts with the material to form a polar oxidation product such as —OH, thereby resulting in discrete hydrophilic regions separated from each other by hydrophobic regions. The degree of hydrophilicity of the discrete regions may be tailored by controlling the concentration of the reactive species, the ultraviolet light intensity, the temperature to which the material is heated, and exposure time. End products made with the methods are suitable for use in a biomolecular array.Type: GrantFiled: April 22, 2003Date of Patent: September 26, 2006Assignee: International Business Machines CorporationInventors: Ho-Cheol Kim, Robert Dennis Miller
