Publication number: 20030232938Abstract: A method of free radical polymerization and for cleaving a thio group from the resulting polymer is provided. The method comprises forming a mixture of one or more monomers, at least one free radical source and a control agent, wherein the control agent comprises a thio moiety. The mixture is polymerized, and the resulting polymer is mixed with a free radical source, and optionally an addition fragmentation agent under cleavage conditions. The thio moiety on the polymer is replaced with a group of interest.Type: ApplicationFiled: April 3, 2003Publication date: December 18, 2003Applicant: Symyx Technologies, Inc.Inventors: Dominique Charmot, Han Ting Chang, Wenyue Wang, Marcelo Piotti

Patent number: 6649708Abstract: To provide a process for producing polymer particles which are spherical and have smooth surfaces and small contents of oil- and the solvent-soluble at the time of being compounded. Polymer particles are produced by adding 0.099 to 47 parts by mass of a crosslinking vinyl monomer to 100 parts by mass of a vinyl monomer (referred to hereinafter as the monomer) during polymerization reaction at a degree of monomer polymerization of 1 to 100% in order to polymerize the monomer in a solvent in the presence of a dispersant and a polymerization initiator to give polymer particles.Type: GrantFiled: December 17, 2001Date of Patent: November 18, 2003Assignee: Kao CorporationInventors: Makoto Tsuji, Yasushi Sasaki

Patent number: 6649715Abstract: Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices using refractive properties of the polymers. Perfluorocyclobutane (PFCB) polymers having aryl groups alternating on an ether chain have shown useful physical properties for optical waveguide applications. Processes for micromolding such polymeric films by replicating a pattern or image directly from a silicon master, rather than from a polydimethyl siloxane (PDMS) mold, are disclosed.Type: GrantFiled: June 27, 2000Date of Patent: November 18, 2003Assignee: Clemson UniversityInventors: Dennis W. Smith, Hiren V. Shah, John Ballato, Stephen Foulger

Patent number: 6576729Abstract: Disclosed herein are methods for producing a polymer. One polymerizes monomers selected from alkene monomers and terminal alkyne monomers, in the presence of a catalyst which is a silylene. The catalyst can be a heterocyclic amido silylene which is at least partially unsaturated within the ring. Also disclosed are polymers produced by the above methods, and improved methods for producing the catalysts.Type: GrantFiled: September 27, 2001Date of Patent: June 10, 2003Assignee: Wisconsin Alumni Research FoundationInventors: Robert C. West, Daniel F. Moser, Michael P. Haaf
