  • Patent number: 10919823
    Abstract: A chlorinolysis process for producing carbon tetrachloride comprising providing a chlorination zone at an operating temperature of from 400 to 600° C. with i) chlorine, ii) a C1 chlorinated compound comprising 1 to 3 chlorine atoms and iii) a carbon/second chlorine source to produce a reaction mixture, and, after a residence time, extracting a product mixture from the chlorination zone, the product mixture comprising carbon tetrachloride and optionally perchloroethylene, wherein the product mixture comprises a higher molar content of carbon tetrachloride than perchloroethylene, if present.

  • Patent number: 10626209
    Abstract: The present invention relates to the preparation and use of copolymers composed of N-(2-hydroxypropyl) methacrylamide (HPMAA) and carboxybetaine methacrylamide (CBMAA). The invention further describes polymer brushes having structure I S—R-polymer??(I) wherein S is a substrate; R is a residue of a polymerization initiator or a RAFT agent bound to the substrate; and “polymer” is the copolymer of N-(2-hydroxypropyl) methacrylamide and carboxybetaine methacrylamide Furthermore, production of these polymer brushes, containing random or block copolymers grafted to or from a substrate is described. The copolymer brushes are suitable for protecting substrates from deposition and/or adhesion of biological substances, and/or against thrombus formation. The brushes functionalized by covalent attachment of bioactive substances to CBMAA monomer units are particularly suitable for specific interaction with target biological substances which is not affected by nonspecific deposition of non-target compounds.

  • Patent number: 4609382
    Abstract: The wear on machine components is reduced during processing of solids concentrates containing abrasive solids if solids concentrates in which the carrier material has a resistance to shear and/or deformation which is the same as or higher than that of the polymer to be provided with the solids concentrate are employed.

  • Patent number: 4105735
    Abstract: A process for flameproofing plastics comprising incorporating in the plastic a homogeneous granulate containing pulverulent red phosphorus with a particle size of up to about 100 microns and a binder; the granulate is more particularly comprised of a blend of10-97% by weight of red phosphorus,3-50% by weight of a binder melting between about 30.degree. and 180.degree. C. and being selected from waxes and/or waxy substances and/or metal soaps, and up to 87% by weight of addends promoting the flameproofing efficiency of the granulate, inhibiting the evolution of gaseous phosphines upon the incorporation of the granulate with the plastics, or being suitable fillers.
