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

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.

标 题:Synthesis of polydiene rubber by high solids solution polymerization

摘要:Synthetic elastomers are typically made commercially by employing emulsion polymerization or solution polymerization techniques. In such solution polymerization techniques, it is desirable to operate at the highest solids content which is practical. As a general rule, it is not practical to prepare such rubbers by solution polymerization at solids contents of higher than about 20 percent. However, the subject invention reveals a technique for preparing such rubbers by high solids solution polymerization at extremely high solids contents. This technique offers substantial advantages associated with eliminating large quantities of organic solvents. The subject invention more specifically relates to a process for the synthesis of polyidene rubber by continuous high solids polymerization which comprises: (1) continuously charging at least one diene monomer, at least one organolithium compound, and from about 4 to about 50 phm of at least one organic solvent into a reaction zone; (2) allowing the monomers to polymerize to a conversion of at least about 90% while utilizing conditions under which there is sufficient evaporative cooling in said reaction zone to maintain a temperature within the range of about 10° C. to about 150° C.; and (3) continuously withdrawing said polydiene rubber from the reaction zone.

摘要:The present invention provides a template-directed self-assembly strategy to integrate the class of materials called dendrimers with periodic mesoporous and macroporous silica materials to create two totally new classes of organic/inorganic nanocomposite materials, which we call periodic mesoporous dendrisilicas (PMeDs) and periodic macroporous dendrisilicas (PMaDs). The unusual combination of inorganic silica and organic dendrimer chemical structures with these scales of porosity and surfaces suggests a myriad of uses for PMeDs and PMaDs, such as the controlled release and uptake of chemicals, chiral separations and catalysis, electronic printing and microelectronic packaging, biomaterial platforms, chromatography stationary phase, and photonic crystal applications. These applications target the synergistic relationship between the dendrimer and the meso- or macroporous structure within a single hierarchical nanostructured organic/inorganic hybrid material.

摘要:Nanocomposite thin films with low dielectric constants are made by the simultaneous deposition of an oxide dielectric and an organic polymer at near room temperatures. Suitable oxides include SiO 2 , and suitable organic polymers include poly(chloro-para-xylylene). The two dielectric materials, when deposited, form nanocomposites characterized by nanometer-sized domains of dielectric material. The nanocomposite thin films of this invention are useful as dielectric layers for interlevel dielectric (ILD) and intermetal dielectric (IMD) dielectrics in the manufacture of semiconductor devices as well as for thin films for flat panel displays, food wraps, hybrid ceramics, glass, hard disk drives, and optical disk drives. Additionally, the invention comprises semiconductor devices and semiconductor chips made incorporating nanocomposites deposited by chemical vapor deposition.
