  • Methods for producing thermoplastic fluoropolymers
    Patent number: 7544765
    Abstract: A process for producing a class of polyarylenes having p-bis-(chlorodifluoromethyl) benzene or p-bis(bromodifluoromethyl) benzene as a comonomer. The p-bis-(chlorodifluoromethyl) benzene or the p-bis(bromodifluoromethyl)benzene act as precursors in a polycondensation reaction with a difunctional monomer.
    Type: Grant
    Filed: October 12, 2006
    Date of Patent: June 9, 2009
    Assignees: University of Florida Research Foundation, Inc., Arkema Inc.

  • Perlited Portland cement plaster joint compound additive with lime
    Patent number: 6902614
    Abstract: A composition and method for treating a surface is described. In one embodiment, the composition comprises about 10% to 90% by weight of cement, about 10% to 90% by weight of plaster, about 0.01% to about 20% by weight of lime, and about 0% to about 30% by weight of perlite. In another embodiment, the composition comprises plaster, cement, perlite, lime, joint compound and water, wherein the plaster, cement, perlite, and lime are in a ratio of about 10-90: 10-90: 0-30: 0.01-20 by weight. In another embodiment, the composition is prepared by a method comprising: (a) providing a first mixture comprising plaster, cement, perlite, and lime; (b) converting the first mixture to a second mixture by a method selected from the group consisting of stirring the first mixture, passing the first mixture through a strainer, and milling the first mixture; and (c) mixing the second mixture with joint compound and water to obtain the composition.
