    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 :Direct synthesis by living cationic polymerization of nitrogen-containing polymers
    发明人:CHERADAME HERVE M; CHEN FRANK J; STANAT JON E R; NGUYEN HUNG A; TABAR BEHROOZ R
    权利人:EXXON CHEMICAL PATENTS INC
    摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

    标 题:Diimine metal complexes, methods of synthesis, and methods of using in oligomerization and polymerization
    发明人:SMALL BROOKE L; CARNEY MICHAEL
    权利人:CHEVRON PHILLIPS CHEMICAL CO
    摘要:Novel α-diimine metal complexes, particularly iron complexes, having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are disclosed. The α-diimine metal complexes having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are produced by forming one of the α-diimine metal complex imine bonds in the presence of a metal salt or an α-acylimine metal complex. The α-diimine metal complexes having phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are useful for polymerizing or oligomerizing olefins.
