发明人：CHAUVIN YVES; COMMEREUC DOMINIQUE; SUGIER ANDRE
权利人:INST FRANCAIS DU PETROLE
摘要:Methane is obtained by reacting hydrogen with carbon monoxide in the presence of a catalyst manufactured by reacting a nickel compound with a reducing aluminum compound in the presence of a titanium compound. The aluminum compound is preferably a trialkylaluminum compound and the atomic ratio of aluminum to (nickel + titanium) is preferably from 1/1 to 20/1.

权利人:ALLIED COLLOIDS LTD
摘要:An ester interchange process, preferably for the formation of vinyl higher esters from methyl acrylate or methacrylate, is conducted in the presence of a novel alcoholate of the formula [M1(OR4)2-aRa6]x[M2(OR4)n-bRb6]y I wherein M1 is selected from Mg, Ca and Ba M2 is selected from Ti, Zr and Al n is 3 or 4 and is the valency of M2 a is a number from 0 to 1.5 b is a number from 0 to 0.75n x+Y=1 and each is a number from 0.005 to 0.995 and is such that the compound is liquid at 30 DEG 0 C. R4 is selected from alkyl having at least 4 carbon atoms, cycloalkyl having at least 4 carbon atoms and aminoalkyl, and each group R6 is individually selected from C1-3 alkoxy and blocking groups that are substantially less reactive in the ester interchange reaction than the groups OR4.

标题 :Synthesis of polycarbonate from dialkyl carbonate and bisphenol diester
发明人：BOLON DONALD A; HALLGREN JOHN E
权利人:GEN ELECTRIC
摘要:Polycarbonates are formed by the interaction of a bisphenol diester, carbon monoxide and oxygen. The initial polycarbonate product is an oligomer which, upon heat treatment, polymerizes to a high molecular weight polycarbonate. The products produced according to the present invention are chainstopped prior to heat treatment, making them less thermally and oxidatively sensitive.

权利人:WANG LIANG; WANG VIKTORIA
摘要:The present invention relates to polyurethane-urea elastomers with exceptional mechanical properties and enhanced elasticity based on molecular structure analysis. The present invention involves the synthesis of a polyurethane-urea elastomer using a combination of commercially available materials: (1) polyols with ultralow unsaturation and narrow polydispersity, (2) diisocyanates with symmetric steric conformation, and (3) bulky diamines between functional groups. The preparation method for the novel polyurethane-urea is disclosed. The subject elastomers have the highest reported elongation-at-break among known polyurethane elastomers.
