Patent number: 5976403Abstract: A process for producing dispersions of atmospherically stable, coated alkali metal particles and atmospherically stable, coated alkali metal powders by agitating a mixture of molten alkali metal in a hydrocarbon oil at dispersion speeds, optionally in the presence of a dispersing agent, contacting the molten alkali metal-hydrocarbon oil dispersion, above or below the surface of the dispersion, with up to 3 weight percent anhydrous carbon dioxide while agitating the dispersion for at least 1 minute. The dispersion in oil can be used directly in chemical reactions. The bulk of the oil can be removed from the dispersions to produce oil wet particles, the oil wet particles car be washed with a low boiling hydrocarbon to produce hydrocarbon wet particles which can be dried to produce atmospherically stable powders of coated metal particles. The dispersed particles in oil, the oil wet particles, the hydrocarbon wet particles and the atmospherically stable powders can each be used in chemical reactions.Type: GrantFiled: April 23, 1998Date of Patent: November 2, 1999Assignee: FMC CorporationInventors: B.

Patent number: 5919870Abstract: Protected functional initiators have been demonstrated to polymerize dienes and alkenyl substituted aromatics. The resultant living anions were linked with a coupling agent, such as divinylbenzene or tin tetrachloride, to afford a protected functionalized star polymer. Subsequent deprotection afforded a star polymer, with functional groups on the end of each arm of the star. The star polymer could be hydrogenated before or after removal of the protecting groups. The newly liberated functional groups can participate in further polymerization chemistry.Type: GrantFiled: June 5, 1996Date of Patent: July 6, 1999Assignee: FMC CorporationInventors: Robert J.
