标 题 :Process for the synthesis of styrene-isoprene rubber
发明人：HSU WEN-LIANG; HALASA ADEL F; MATRANA BARRY A
权利人:GOODYEAR TIRE & RUBBER
摘要:The subject invention relates to a technique for synthesizing rubbery copolymers of styrene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire tread rubber compounds. By utilizing these styrene-isoprene rubbers in tire treads, tires having improved wet skid resistance can be built without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a process for the synthesis of styrene-isoprene rubbers which comprises copolymerizing isoprene monomer and styrene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) an alkyl tetrahydrofurfuryl ether modifier, wherein the molar ratio of the modifier to the lithitium initiator is within the range of 2:1 to 40:1. The subject invention further discloses a process for the synthesis of styrene-isoprene rubbers which comprises copolymerizing isoprene monomer and styrene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) 2,2-ditetrahydrofurylpropane as a modifier, wherein the molar ratio of the modifier to the lithium initiator is within the range of 1:1 to 40:1.

标题:Alkyl tetrahydrofurfuryl ethers as anionic polymerization modifier in the synthesis of rubbery polymer
发明人：HSU WEN-LIANG; HALASA ADEL F; MATRANA BARRY A
权利人:GOODYEAR TIRE & RUBBER
摘要:It has been unexpectedly discovered that various compounds, such as alkyl tetrahydrofurfuryl ethers, can be used to modify anionic polymerizations of conjugated diene monomers. These modifiers can be used to polymerize isoprene monomer into high 3,4-polyisoprene at excellent polymerization rates. This is in contrast to the modifiers such as tetramethylethylene diamine which are typically used to modify such polymerizations. This invention more specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) a modifier which is an alkyltetrahydrofurfuryl ether selected from the group consisting of ethyltetrahydrofurfuryl ether, propyltetrahydrofurfuryl ether, and butyltetrahydrofurfuryl ether. In the practice of this invention, the utilization of ethyltetrahydrofurfuryl ether is highly preferred since its use results in faster polymerization rates and higher vinyl contents in the resultant polymer.

In the practice of this invention, the utilization of alkyltetrahydrofurfuryl ethers having alkyl groups which contain from 6 to 10 carbon atoms, such as hexyltetrahydrofurfuryl ether, is highly preferred since their use does not results in the creation of odor problems.

摘要:Embodiments of the invention provide methods and materials for chemical cross-coupling reactions that utilize aryl alcohol derivatives as cross-coupling partners. Embodiments of the invention include methods for the amination of aryl sulfamates and carbamates, which are attractive cross-coupling partners, particularly for use in multistep synthesis. Illustrative embodiments include versatile means to use simple derivatives of phenol as precursors to polysubstituted aryl amines, as exemplified by a concise synthesis of the antibacterial drug linezolid.
