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.

发明人：GHELFI FRANCO; FERRANDO ANGELO; LONGO ALDO; BUFFAGNI MIRKO
权利人:VERSALIS SPA
摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.

标题:One-pot synthesis of nanoparticles and liquid polymer for rubber applications
发明人：WARREN SANDRA
权利人:BRIDGESTONE CORP
摘要:A method for performing a one-batch synthesis of a blend of nanoparticles and liquid polymer includes polymerizing a first monomer and optionally a second monomer in a hydrocarbon solvent to form the liquid polymer. The polymerization is terminated before completion with a quenching agent. Then a charge of polymerization initiator, and a mixture of multiple-vinyl aromatic monomer and mono-vinyl aromatic monomer are added. This causes further polymerization whereby nanoparticles are formed in situ having a core including the multiple-vinyl aromatic monomer, and a shell including the first monomer or the first monomer and the second monomer. Liquid polymer/nanoparticle blends resulting from the method and rubber compositions incorporating the blends are also disclosed.

摘要:A process for the synthesis of branched graft polymers comprises acylating a first polymer and grafting thereto a second polymer, the second polymer having reactive groups capable of being bound to the acyl groups on the first polymer. The acylation and grafting steps can be repeated to produce graft polymers having a dendritic architecture. The invention also provides polymers produced by the above process, which may be simple branched (comb) polymers, or dendritic polymers.

标题 :Processes for improving linking efficiencies in the synthesis of star polymers
发明人：QUIRK RODERIC PAUL; LETCHFORD ROBERT JAMES; SCHWINDEMAN JAMES ANTHONY
权利人:FMC CORP
摘要:Processes for the synthesis of star or multi-branched polymers and the resultant polymers. One or more alkadiene monomers are polymerized in the presence of suitable organometallic initiators and subsequently coupled to form star polymers. Prior to coupling, one or more alkenylsubstituted aromatic hydrocarbons are incorporated at the living ends of the polydienyl anions to provide increased linking efficiencies.
