Patent number: 5252247Abstract: Solubilized metal (dialkylaminoalcoholate) compounds in organic solvent can serve as a source of metal values for metal oxide-containing superconductor compositions. Stable solutions, resistant to precipitation problems, can be formed by reaction of a dialkylaminoalkanol with a metal alkoxide followed by removal of by-product alkanol by vacuum distillation below the reflux temperature of the solution. Exemplary metals include copper, yttrium, barium, calcium, and bismuth, lanthanum and strontium.Type: GrantFiled: March 13, 1991Date of Patent: October 12, 1993Assignee: Akzo America Inc.Inventors: Carl C. Greco, Johst H. Burk

Patent number: 5084586Abstract: Disclosed are novel compounds which are useful as initiators for cationically polymerizable monomers. The novel compounds comprise a carbon containing cation (e.g., trimethyloxonium) which is capable of initiating cationic polymerization and a non-nucleophilic counterion which is an at least partially fluorinated hydrocarbylsulfonato metallate (e.g. perfluoroethylsulfonato-aluminate). The disclosed initiators are capable of initiating the cationic polymerization of a wide variety of monomers such as epoxides, tetrahydrofuans, oxazolines, vinyls, lactones, and the like.Type: GrantFiled: February 12, 1990Date of Patent: January 28, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventor: Omar Farooq
