标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

标题:Synthesis of methylaluminoxanes
发明人：CRAPO CLARK C; MALPASS DENNIS B
权利人:TEXAS ALKYLS INC
摘要:Methylaluminoxane can be formed by the reaction of a tetraalkyldialuminoxane containing C 2 or higher alkyl groups with trimethylaluminum with the trimethylaluminum being present in an amount which is not present in stoichiometric excess. Another embodiment of the present invention involves the synthesis of the methylaluminoxane by reaction of a trialkylaluminum compound or a tetraalkyldialuminoxane containing C 2 or higher alkyl groups with water to form a polyalkylaluminoxane which is then reacted with trimethylaluminum. A third embodiment of the present invention involves the synthesis of the methylaluminoxane by reaction of the aforementioned polyalkylaluminoxane with trimethylaluminum and then with water.

权利人:GOODYEAR TIRE & RUBBER
摘要:Crystallizable 3,4-polyisoprene and isoprene-butadiene copolymers having high vinyl contents can be synthesized in organic solvents to quantitative yields after short polymerization times by utilizing the catalyst systems of this invention. The 3,4-polyisoprene made utilizing this catalyst system is strain crystallizable and can be employed in tire treads which provide improved traction and improved cut growth resistance. This invention specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent at a temperature which is within the range of about -10 DEG C. to about 100 DEG C. in the presence of a catalyst system which is comprised of (a) an organoiron compound which is soluble in the organic solvent, wherein the iron in the organoiron compound is in the +3 oxidation state, (b) a partially hydrolyzed organoaluminum compound which was prepared by adding a protonic compound selected from the group consisting of water, alcohols and carboxylic acids to the organoaluminum compound, and (c) a chelating aromatic amine; wherein the molar ratio of the chelating amine to the organoiron compound is within the range of about 0.1:1 to about 1:1, wherein the molar ratio of the organoaluminum compound to the organoiron compound is within the range of about 5:1 to about 200:1, and wherein the molar ratio of the protonic compound to the organoaluminum compound is within the range of about 0.001:1 to about 0.2:1.
