| 20080242791 | Methods of Producing Vinyl Aromatic Polymers Using (Meth)Acrylic Macroinitiators - The present invention relates to the use of poly acrylic and/or methacrylic macroinitiators in the free radical addition reaction of vinyl aromatic monomers to improve the properties of the resulting copolymer and/or composite. More particularly, the present invention relates to the production of poly acrylic and/or poly methacrylic macroinitiators having nitroxyl end groups. Using such macroinitiators in the free radical addition reaction of vinyl aromatics such as polystyrene compatibilizes the acrylic monomer in the vinyl aromatic matrix thereby improving the properties of the resulting polymer. | 10-02-2008 |
| 20080306169 | Method For Preparing a Living Polymer Comprising Methacrylic and/or Methacrylate Units - The invention relates to a method for preparing a living polymer comprising methacrylic and/or methacrylate units using a monofunctional or polyfunctional alkoxyamine consisting in polymerising one or several types of methacrylic an/or methacrylate units. | 12-11-2008 |
| 20090306276 | USE OF COMPOSITE MATERIALS BASED ON CARBON NANOTUBES AS THICKENING AGENTS FOR AQUEOUS SOLUTIONS - The present invention relates to the use of composites based on carbon nanotubes as viscosity enhancers for aqueous solutions, characterized in that said composite comprises carbon nanotubes (CNTs) and at least one hydrophilic (co) polymer. | 12-10-2009 |
| 20100069577 | COPOLYMERS BASED ON METHACRYLATE UNITS, PREPARATION METHOD THEREOF AND USE OF SAME - The invention relates to a method for preparing a copolymer having a backbone based on methacrylate units, comprising a step involving the polymerization of one or more precursor methacrylate monomers of said units in the presence of: a polymerization initiator; at least RAFT-type transfer agent which can generate a primary radical; and at least one comonomer selected from among styrene monomers and acrylate monomers. The invention also relates to the resulting copolymers capable of being obtained according to this process, in particular block copolymers, in particular block copolymers, and to the use thereof as additives for plastic materials. | 03-18-2010 |
| 20100121021 | PROCESS FOR THE PREPARATION OF POLYLACTONES AND POLYLACTAMS - The present invention relates to a process for the preparation of a lactone or lactam homopolymer, comprising the stage consisting in reacting a lactone or lactam with a nonpolymeric initiator comprising at least one hydroxyl or thiol functional group in a nonchlorinated solvent in the presence of a sulfonic acid of formula R—SO | 05-13-2010 |
| 20100121024 | METHOD FOR PRODUCING A COPOLYMER OF AT LEAST ONE CYCLIC MONOMER - The present invention relates to a process for the preparation of a copolymer of at least one cyclic monomer chosen from a lactone, a lactam, a lactide and a glycolide, comprising the stage consisting in reacting said cyclic monomer with a polymeric initiator in the presence of a compound carrying a sulfonic acid functional group. | 05-13-2010 |
| 20100137534 | METHOD FOR PREPARING MICROGEL PARTICLES BY CONTROLLED RADICAL POLYMERIZATION IN AN AQUEOUS DISPERSION USING NITROXIDE CONTROL AGENTS - The invention relates to a method for preparing microgel particles according to a method of controlled radical polymerization in an aqueous dispersion using particular control agents of the nitroxide type.
