标题 :One-pot synthesis of high-quality metal chalcogenide nanocrystals without precursor injection
发明人：CAO YUNWEI CHARLES; CHEN OU
权利人:CAO YUNWEI CHARLES; CHEN OU; UNIV FLORIDA
摘要:A method of forming monodisperse metal chalcogenide nanocrystals without precursor injection, comprising the steps of: combining a metal source, a chalcogen oxide or a chalcogen oxide equivalent, and a fluid comprising a reducing agent in a reaction pot at a first temperature to form a liquid comprising assembly; increasing the temperature of the assembly to a sufficient-temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals; and growing the plurality of metal chalcogenide nanocrystals without injection of either the metal source or the chalcogen oxide at a temperature equal to or greater than the sufficient-temperature, wherein crystal growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals. Well controlled monodispersed CdSe nanocrystals of various sizes can be prepared by choice of the metal source and solvent system.

标 题:Synthesis of 1,4-polybutadiene
发明人：RACHITA MICHAEL JOSEPH; JOHNSON SCOTT EDWARDS
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention is based upon the unexpected discovery that alkylated diphenylamines can be used in conjunction with nickel based catalyst systems which contain (a) an organonickel compound, (b) an organoaluminum compound, and (c) a fluorine containing compound to produce cis-1,4-polybutadiene having reduced molecular weight and an increased level of branching. This results in the cis-1,4-polybutadiene exhibiting good processability without sacrificing cold flow characteristics. Additionally, the alkylated diphenylamine which remains in the rubber acts in a manner which provides it with antioxidant protection. In other words, the use of alkylated diphenylamines accomplishes the three major objectives that are realized by employing para-styrenated diphenylamines (reduced molecular weight, regulated polymer macrostructure through branching and antidegradant protection). However, the utilization of alkylated diphenylamines, unlike para-styrenated diphenylamines, offers the additional advantage of being soluble in aliphatic solvents. By virtue of this increased level of solubility in aliphatic solvents, such as hexane, alkylated diphenylamines can be employed at greatly reduced levels of aromatic solvents. Likewise, when mixed catalyst streams containing alkylated diphenyl amines are combined precipitation is minimized compared to para-styrenated diphenylamine significantly improving issues related to fouling. The subject invention more specifically discloses a process for producing cis-1,4-polybutadiene having a reduced molecular weight and improved processability which comprises polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound, and (d) an alkylated diphenylamine; wherein the alkylated diphenylamine has alkyl groups that contain from 2 to 18 carbon atoms, and wherein the organoaluminum compound and the fluorine containing compound are brought together in the presence of the alkylated diphenylamine.

标 题 :Polysulfide polyols, their production and use in the synthesis of polyurethanes
发明人：BALBO BLOCK MARCO; RHUDY KEVIN; FLECKENSTEIN CHRISTOPH
权利人:BASF SE
摘要:The present invention relates to sulfur containing polyols, a process for their production by reaction of at least one unsaturated alcohol A with elemental sulfur, wherein the unsaturated alcohol A has only one carbon-carbon double bond-unsaturation per molecule. The sulfur containing polyols are used in the production of polyurethanes, in particular rigid foam polyurethanes, for high-temperature pipe insulation applications.
