20100261832 | PROCESS FOR THE PREPARATION OF A FILM OR A COATING ON A SUBSTRATE WITH AN AQUEOUS DISPERSION OF POLYMER PARTICLES AND THE RESULTING FILMS AND COATINGS - “Process for the preparation of a film or coating on a solid substrate, comprising at least one step of applying to the substrate an aqueous dispersion of polymer particles, composed of a mixture, on the one hand, of one or more block copolymers and, on the other hand, of one or more random copolymers and/or homopolymers; or of a coating composition containing said aqueous dispersion. Said coating composition is, in particular, a paint, a composition for the coating of textiles, of leather or of non-woven fabrics; a composition for the coating of paper; an adhesive composition. Film or coating capable of being obtained by this process.” | 10-14-2010 |
20110152454 | PRODUCTION OF GRAFTED POLYETHYLENE FROM RENEW ABLE MATERIALS, THE OBTAINED POLYETHYLENE AND USES THEREOF - The invention relates to a method for production of grafted polyethylene comprising the following steps: a) fermentation of primary renewable material with optional purification to give at least one alcohol chosen from ethanol or a mixture of alcohols comprising ethanol; b) dehydration of the alcohol obtained to give in a first reactor at least one alkene selected from ethylene and mixtures of alkenes containing ethylene and optional purification of the alkene to give ethylene; c) polymerization, in a second reactor, of the ethylene to give polyethylene; d) isolation of the polyethylene obtained in step c); e) grafting the polyethylene with at least one grafting monomer selected from the unsaturated carboxylic acids or theifunctional derivatives thereof, the unsaturated dicarboxylic acids having 4-10 carbon atoms and the functional derivatives thereof being C | 06-23-2011 |
20110196114 | POLYOLEFIN DERIVED FROM RENEWABLE RESOURCES, AND METHOD FOR PRODUCING SAME - The invention relates to a polymer obtained by polymerizing olefins having 6 to 9 carbon atoms and partially derived from renewable resources. In particular, the polymer according to the invention can be derived from vegetable oil or animal fat. The invention also relates to the method for producing the polymer. | 08-11-2011 |
