标题:Highlights Of Drought Policy And Related Science In Australia And The U.S.A.
摘要:Patterns Of Water Supply And Use In Australia And The U.S.A. Differ In Many Ways. This Results In Different Perceptions Concerning The Nature Of Drought And Policy Approaches To Its Management. This Paper Discusses The Differences And Similarities And Explores Lessons That Policy Makers In Both Countries Can Learn From One Another. A Key Difference Between The Two Countries Is That Whereas Drought Is Perceived In Australia Essentially In Terms Of Its Impact On Agriculture,In The U.S. Both Perceptions And Policy Are Also Heavily Influenced By The Impact Of Drought On Urban Communities. This Has Led To Different Policy Emphases. In 1992 Australia Established Its National Drought Policy; The U.S. Is Presently Considering The Adoption Of A National Drought Policy. These Policies Highlight Drought Being Accepted As Part Of Natural Climate Variability,Rather Than As A Natural Disaster. They Also Emphasize The Protection Of The Natural Resource Base.

标 题 :Process for the synthesis of cumene hydroperoxide
发明人：CODIGNOLA FRANCO
权利人:EUROTECHNICA DEV & LICENSING S
摘要:This invention refers to a process for the synthesis of cumene hydroperoxide and to the product thus obtained. n More in particular, this invention refers to a process for the production of cumene hydroperoxide by oxidating cumene with oxygen, where this process is run in the presence of a basic medium insoluble in the reaction environment, and such as not to release inorganic cations to the reaction environment. Such a basic medium is preferably a pyridinic resin. n The cumene hydroperoxide thus obtained, characterized by the fact of being free of inorganic cations, is a further object of the invention.

标 题 :Activated esters for synthesis of sulfonated telechelic polycarbonates
发明人：BRUNELLE DANIEL J; COLONNA MARTINO; FIORINI MAURIZIO; BERTI CORRADO; BINASSI ENRICO
权利人:GEN ELECTRIC
摘要:A process of making a sulfonated telechelic polycarbonate is described. A dihydroxy compound, a carbonate ester, and an activated ester of a sulfobenzoic acid salt are reacted together. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.

标 题 :Synthesis of phenolic monomers containing imide or diimide moieties and high heat carbonate polymers prepared therefrom
发明人：AMERIK VALENTINA; HOEKS THEODORUS L; LIKIBI PARFAIT JEAN MARIE; NELSON MARK
权利人:GEN ELECTRIC
摘要:A process has been surprisingly discovered that can produce a high heat carbonate polymer (i.e., one with a Tg greater that 150° C.), without the drawbacks encountered in attempts to produce a high heat carbonate polymer. The process of the instant invention comprises the steps of: n (1) reacting an aromatic amine with a dihydric phenol to prepare an aminophenol; n (2) reacting an anhydride or dianhydride with the aminophenol to prepare a phenolic precursor; and n (3) reacting the phenolic precursor with a carbonate precursor to prepare a high heat carbonate polymer.

标 题 :Phosphine ligand promoted synthesis of tetraaryloxyalkane
发明人：HAITKO DEBORAH ANN; GRADE MARSHA MOTTEL; LONGLEY KATHRYN LYNN; COLBORN ROBERT EDGAR
权利人:GEN ELECTRIC
摘要:Addition of phosphine ligands can produce high yields of tetraphenoxymethane, TPM, and diphenylcarbonate, DPC, in short reaction times and improved reaction rates by a copper-induced condensation of phenol and carbon disulfide, CS 2 . Either aromatic or aliphatic substituted phosphine ligands can be employed. The copper(I) oxide utilization is significantly improved in reactions containing phosphine ligands, such that yields exceeding 100% tetraphenoxymethane are observed. Some of the sulfur-containing byproduct is transferred to the phosphine in the form of phosphine sulfide.

标 题:Process for synthesis of polyestercarbonate-siloxane copolymers
发明人：HAWKINS CHRISTOPHER M; ROSENQUIST NILES R
权利人:GEN ELECTRIC
摘要:A process for synthesizing polyestercarbonate-siloxane copolymers which have a smaller concentration of low molecular weight species and greater thermal stability has been described. Essentially the process includes adding the comonomer, diacid chloride siloxane, after approximately 1/3 of the phosgene has been added, in a conventional interfacial copolymerization, (as opposed to addition at the beginning of the polymerization).
