标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
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.

标题 :Synthesis of cis-1,4-polyisoprene rubber
发明人：CASTNER KENNETH FLOYD
权利人:GOODYEAR TIRE & RUBBER
摘要:The synthesis of cis-1,4-polyisoprene by polymerizing isoprene with a catalyst system which is comprised of a titanium tetrahalide, a trialkylaluminum compound and diphenylether is plagued with the formation of gel. This invention is based upon the unexpected discovery that gel formation can be reduced by conducting such polymerizations in the presence of a diarylamine, such as para-styrenated diphenylamine. The subject invention more specifically discloses a process for synthesizing cis-1,4-polyisoprene having a low gel content which comprises polymerizing isoprene in an inert organic solvent with a preformed catalyst system which is made by reacting an organoaluminum compound with titanium tetrahalide, such as titanium tetrachloride, in the presence of at least one ether, wherein said polymerization is conducted at a temperature which is within the range of about 0 DEG C. to about 100 DEG C., and wherein said polymerization is conducted in the presence of a diarylamine.
