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.

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.

摘要:The present invention provides a method of synthesizing fluorided metallocene catalyst components comprising contacting at least one fluoriding agent comprising fluorine with one or more alkylated metallocene catalyst components comprising one or more non-halogen leaving groups to produce a fluorided catalyst component; wherein from less than 3 equivalents of fluorine are contacted for every equivalent of leaving group. The method of the invention is exemplified by the following reaction which takes place in a non-coordinating diluent such as pentane: n n nwherein one or both of the “Cpâ€? rings may be substituted with an R group as described herein, and may be bridged. The reaction can be run at any desirable temperature, desirably between 10° C. and 35° C. The reaction product of the BF 3 and dimethyl zirconocene is the fluorided zirconocene. The mole ratio of the BF 3 fluoriding agent and the starting metallocene is less than 2:1 (fluoriding agent:metallocene) in one embodiment, and less than or equal to 1.6:1 in a particular embodiment, and less than or equal to 1.5:1 in a more particular embodiment, and less than or equal to 1.2:1 in yet a more particular mbodiment.
