标 题 :Process for the synthesis of isoprene butadiene rubber
发明人：BELL ANTHONY J; MATRANA BARRY A; HALASA ADEL F
权利人:GOODYEAR TIRE & RUBBER
摘要:The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.

摘要:IN THE POLYMERIZATION OF ETHYLENE TO ALPHA OLEFINS WITH A CATALYST COMPRISING TRIETHYLALUMINUM AND NICKEL THE PRESENCE OF DIPHENYL ETHER IS KNOWN TO INHIBIT PRODUCTION OF ALPHA OLEFINS OF CHAIN LENGTH REQUIRED FOR SYNTHESIS OF BIODEGRADABLE DETERGENTS. HOWEVER, WHEN ETHYLENE IS TELOMERIZED WITH A CATALYST COMPRISING ALKYL ALUMINUM SESQUICHLORIDE AND TITANIUM TETRACHLORIDE THE PRESENCE OF DIPHENYL ETHER IS SHOWN TO HAVE AN OPPOSITE EFFECT WHEREBY THE PRODUCTION OF ALKYL GROUPS OF CHAIN LENGTH REQUIRED FOR SYNTHESIS OF BIODEGRADABLE DETERGENTS IS INCREASED.

标题:Catalytic synthesis of delta-valerolactone (dvl) from furfural-derived 2-hydroxytetrahydropyran (hthp)

摘要:A method to make delta-valerolactone (“DVLâ€?) by dehydrogenating 2-hydroxytetrahydropyran (“HTHPâ€?). The HTHP is contacted with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL via dehydrogenation of the HTHP. The HTHP may be derived from biomass. Thus, the method yields DVL without requiring a petroleum-based feedstock.

发明人：THIELE SVEN K H; MONROY VICTOR M; WILSON DAVID R
摘要:Random or block co- or terpolymers produced by using metal complex catalysts in a reaction of one conjugated diene monomer with one aromatic Random or block co- or terpolymers produced by using metomers with one aromatic α-olefin or terpolymers of one conjugated diene monomer with one aromatic α-olefin and one aliphatic α-olefin by using metal complexes comprising metals of group 3 to 10 of the Periodic System of the Elements in combination with activators and optionally a support material. More particularly the metal complexes used for the synthesis of co- or terpolymer are lanthanide metals. Even more particularly diene monomer(s) and aromatic α-olefin monomer(s) such as, but not limited to, butadiene and styrene or isoprene and styrene are copolymerized giving random or block copolymers or butadiene, styrene and isoprene are terpolymerized giving random or block terpolymers using metal complexes comprising lanthanide metals in combination with activators and optionally a support material. Preferably random co- or terpolymers are formed.
