  • Synthesis method for polymers by controlled radical polymerisation with xanthates
    Patent number: 7285610
    Abstract: A polymer composition and method of preparing same is described wherein an ethylenically unsaturated monomer is contacted with a source of free radicals and a compound of formula (1A), (1B) and (1C) as defined herein. The polymer composition may be a homopolymer or a block copolymer.
    Type: Grant
    Filed: September 16, 2004
    Date of Patent: October 23, 2007
    Assignee: Rhodia Chimie
    Inventors: Mathias Destarac, Dominique Charmot, Samir Zard, Isabelle Gauthier-Gillaizeau
  • Insulating wall assembly, and structure including the same
    Publication number: 20070074474
    Abstract: An insulating wall assembly including a substantially rectangular framework having opposite interior and exterior sides, the framework including a plurality of vertical support studs mounted to a plurality of horizontal end studs so as to define at least one inner spacing within the framework, the vertical support studs and the horizontal end studs having each opposite front and rear sides corresponding to the interior and exterior sides of the framework. A foam of water-based polyurethane is injected into said at least one inner spacing so as to complete fill the same and provide the wall assembly with insulating capabilities. Outer components are mounted respectively onto the interior and exterior sides of the framework so as to close up the framework and provide the wall assembly with additional insulating capabilities.
