The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.
专利号:US-8067633-B2 优先权日:2006-12-05 标 题:Method for the synthesis of (meth)acrylic esters catalysed by a polyol titanate 发明人:PAUL JEAN-MICHEL 权利人:PAUL JEAN-MICHEL; ARKEMA FRANCE 摘要:The subject of the invention is a method for the synthesis of (meth)acrylic esters by transesterification in the presence of a catalyst corresponding to the formula [(R′O) 3 Ti] x R″ in which R′ is a linear or branched alkyl radical having from 2 to 8 carbon atoms which may contain heteroatoms or R′ is a phenyl radical, R′ is a polyfunctional radical, originating from a polyol R′(OH) x comprising x alcohol functional groups and x is an integer ranging from 2 to 6. The method according to the invention is particularly well suited to the synthesis of dialkylaminoalkyl (meth)acrylates from methyl (meth)acrylate and a dialkylaminoalcohol.
专利号:US-9788548-B2 优先权日:2013-12-13 标题:Synthesis of pure diallyl morpholinium monomers in high yields and using antibacterial effect of their spiro polymers 发明人:BICAK TUGRUL CEM; INCE AHMET; BICAK NIYAZI 权利人:BICAK TUGRUL CEM; Tugrul Cem BICAK 摘要:Herein, the synthesis of N,Ndiallyl morpholinium monomers and polymerization of the same to form rings at high yield and purity are explained. The process involves the synthesis of N,Ndiallyl morpholinium bromide and chloride and subsequently partially or completely exchanging their anions with borate, p-toluenesulfonate, oleate, and acetate anions. The cyclopolimerization of monomers yields water soluble polymers carrying quaternary ammonium groups in each repeated unit, whose aqueous solutions act as a bactericide solution. These solutions are advantageous in preparation of antibacterial formulations intended for domestic use. The polymer with bromide and borate anions is an efficient antibacterial which is able to kill “ Pseudomonas Aeruginosa â€?, the hardest hospital bacterium to cope with, as well as various common bacteria. These formulations are suitable for producing bactericide wet wipes and forming abacterial surfaces and, when combined with air conditioners, generating bacteria free air.
专利号:US-6512081-B1 优先权日:1997-07-21 标题:Synthesis of dithioester chain transfer agents and use of bis(thioacyl) disulfides or dithioesters as chain transfer agents 发明人:RIZZARDO ENZIO; THANG SAN HOA; MOAD GRAEME 权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG 摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.
专利号:US-9126196-B2 优先权日:2009-05-26 标题 :Composition including dialkyl tin oxide and use thereof as a transesterification catalyst for the synthesis of (meth) acrylic esters 发明人:PAUL JEAN-MICHEL; TONNELIER BORIS; AUGUSTIN FRANCIS 权利人:PAUL JEAN-MICHEL; TONNELIER BORIS; AUGUSTIN FRANCIS; ARKEMA FRANCE 摘要:The present invention relates to a composition including a dialkyl tin oxide, such as DBTO, which can be used as a transesterification catalyst for the synthesis of (meth)acrylic esters. The invention also relates to a method for the synthesis of (meth)acrylic esters by transesterification in the presence of said composition.
专利号:US-10023677-B2 优先权日:2014-12-16 标 题 :Method for controlling the synthesis of a block copolymer containing at least one nonpolar block and at least one polar block and use of said block copolymer in applications of nanolithography by direct self-assembly 发明人:NAVARRO CHRISTOPHE; NICOLET CELIA; CHEVALIER XAVIER 权利人:ARKEMA FRANCE 摘要:A method for controlling the synthesis of a block copolymer containing at least two blocks, with at least one nonpolar block and at least one polar block, said method making it possible in particular to control the ratio between the blocks and the molecular weight of each of the blocks, said copolymer being a block copolymer intended to be used as a mask in a method of nanolithography by direct self-assembly (DSA), said control being achieved by semicontinuous anionic polymerization in an aprotic nonpolar medium.
