  • Alkoxysilacycloalkanes, process for their preparation and their use for the polymerization of olefins
    Patent number: 7049454
    Abstract: The invention relates to alkoxysilacycloalkanes, to the process of their preparation and to their use in the polymerization of olefins. The introduction of these alkoxysilacycloalkanes into the olefin polymerization environment makes it possible to raise the heptane-insolubles content of the polymer finally formed.
    Type: Grant
    Filed: July 15, 2003
    Date of Patent: May 23, 2006
    Assignee: Arkema
    Inventors: Claude Grison, Valerie Barthel, Delphine Batt-Coutrot, Philippe Coutrot, Thierry Saudemont, Jean-Michel Brusson, Jean Malinge, Claude Brun, Corinne Meynard

  • Production of plastic foams, preferably rigid foams containing urethane groups or urethane and isocyanurate groups, and blowing agent-containing emulsions for this purpose
    Patent number: 5300534
    Abstract: A process for the production of plastic foams, preferably rigid foams containing urethane groups or urethane and isocyanurate groups, by reactinga) an organic and/or modified organic polyisocyanate withb) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and, if desired,c) a low-molecular-weight chain extender and/or cross-linking agent,in the presence ofd) a blowing agent,e) a catalyst and, if desired,f) assistants and/or additives,in which the blowing agent (d) used is at least one vinylfluoroalkane of the formula CH.sub.2 .dbd.CH--C.sub.n F.sub.
