权利人:DUBOIS JEAN-LUC; ARKEMA FRANCE
摘要:The invention relates to a method for the synthesis of diacids of general formula ROOC—(CH 2 ) n —(CHâ•?CH) a —(CH 2 ) m COOR 1 in which n and m are identical or different and each represent an integer such that their sum is between 6 and 15, a is an index of 0 or 1, and R and R 1 are H or an alkyl radical with 1 to 4 carbon atoms, from long-chain mono-unsaturated natural fatty acids or esters having at least 10 adjacent carbon atoms per molecule of the general formula CH 3 —(CH 2 ) p —CHâ•?CH—(CH 2 ) q —COOR, p and q, being identical or different and representing indices between 2 and 11, wherein said method comprises the first step of oxidizing by fermentation said natural fatty acid or ester, using a microorganism, such as a bacterium, a yeast, or a fungus, into at least one unsaturated dicarboxylic acid or dicarboxylate, the second step of submitting the product from the first step to a metathesis crossed with a compound of formula R 2 OOC—(CH 2 ) x —CHâ•?CH—R 3 , in which R 2 is H or an alkyl radical with 1 to 4 carbon atoms, x is 0 or 1 or 2, and R 3 is H, CH 3 or COOR 2 , in order to obtain the unsaturated compound of formula ROOC—(CH 2 ) q —CHâ•?CH—(CH 2 ) x —COOR 2 , and the third optional step of converting the usaturated compound into a saturated compound by hydrogenation of the double bond.

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.
