20150119523 | CONTROLLED FREE-RADICAL COPOLYMERIZATION OF TRIFLUOROETHYLENE - The invention concerns a method for preparing block copolymers, comprising a step of controlled free-radical copolymerisation of trifluoroethylene with at least one additional monomer, different from trifluoroethylene, in the presence of a chain transfer agent, said chain transfer agent being a xanthate compound, a trithiocarbonate compound or a monoiodide compound. The invention also concerns the block copolymers likely to be obtained by this method. | 04-30-2015 |
20140154611 | CONTROLLED RADICAL COPOLYMERIZATION OF FLUORINATED MONOMERS BY XANTHATE OR TRITHIOCARBONATE - The invention relates to a method of preparing a fluorinated copolymer, comprising a step of copolymerization of a fluorinated monomer (of the vinylidene fluoride type) with an α-trifluoromethacrylic acid monomer or derivative of α-trifluoromethacrylic acid, in the presence of a xanthate or trithiocarbonate compound. The invention also relates to copolymers obtained by this method as well as block copolymers comprising a copolymer block prepared according to this method. | 06-05-2014 |
20130165667 | METHOD FOR THE PREPARATION OF PHOSPHINE BUTADIENE LIGANDS, COMPLEXES THEREOF WITH COPPER AND USE THEREOF IN CATALYSIS - A method for the creation of a carbon-carbon (C—C) bond or of a carbon-heteroatom (C-HE) bond includes reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) capable of replacing the leaving group, thus creating a C—C or C-HE bond, in which process the reaction is carried out in the presence of an effective amount of a catalytic system comprising at least one copper/butadienylphosphine complex. | 06-27-2013 |
20110190404 | FLUOROCARBON POLYMER MATERIAL AND METHOD FOR SYNTHESIZING - The invention relates to a fluorocarbon polymer material comprising a backbone with the following unit: | 08-04-2011 |
20100121076 | METHOD FOR THE PREPARATION OF PHOSPHINE BUTADIENE LIGANDS, COMPLEXES THEREOF WITH COPPER AND USE THEREOF IN CATALYSIS - The present invention relates to a method for preparing phosphine butadiene-type ligands, and their use, particularly as catalytic metal ligands used in the reactions leading to the formation of carbon-carbon and carbon-heteroatom bonds. | 05-13-2010 |
20090326240 | Iron-Copper Co-Catalyzed Process for Carbon-Carbon or Carbon-Heteroatom Bonding - The present invention relates to a process for creating a Carbon-Carbon bond (C—C) or a Carbon-Heteroatom bond (C—HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C—C or C—HE bond, wherein the reaction takes place in the presence of an effective quantity of a catalytic system comprising iron and copper. | 12-31-2009 |
