摘要:
The present invention relates to a method for producing metal nanoparticles and metal nanoparticles produced thereby, in particular, to a method for producing metal nanoparticles used for inkjet that comprises, preparing metal nanoparticles capped with a fatty acid; heating a mixture of the capped metal nanoparticles and a linear or branched first amine of C1-C7 so that a part of the fatty acid is substituted to the first amine; and heating after adding a linear or branched second amine of C8-C20 to the mixture so that the first amine is re-substituted to the second amine. According to the present invention, metal nanoparticles capped with 2 kinds of dispersants can be produced massively, and its application to ink for inkjet technique can lower the curing temperature of ink.
摘要:
One aspect of the present invention relates to ligands for transition metals. A second aspect of the present invention relates to the use of catalysts comprising these ligands in transition metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject methods provide improvements in many features of the transition metal-catalyzed reactions, including the range of suitable substrates, reaction conditions, and efficiency.
摘要:
The present invention relates to a process for the production of a catalyst by reacting metal compounds with azo ligands, the catalyst, the use of this catalyst as a polymerization catalyst, a process for olefin (co)polymerization with the aid of these catalysts, reaction products of these catalysts with co-catalysts, the olefin (co)polymer, the use of this olefin (co)polymer for the production of molded parts and also molded parts produced from the olefin (co)catalyst.
摘要:
Olefins are polymerized by novel transition metal complexes of selected iminocarboxylate and iminoamido ligands, sometimes in the presence of cocatalysts such as alkylaluminum compounds or neutral Lewis acids. Olefins which may be (co)polymerized include ethylene, α-olefins, and olefins containing polar groups such as olefinic esters for example acrylate esters. Also described are certain “Zwitterionic” transition metal complexes as polymerization catalysts for making polar copolymers. The resulting polymers are useful as thermoplastics and elastomers.
摘要:
The present invention relates to a process for preparing highly pure tris-ortho-metalated organometallic compounds and to pure organometallic compounds of this type, especially compounds of the d8 metals, which may find use as coloring components in the near future as active components (=functional materials) in a series of different types of applications which can be classified within the electronics industry in the widest sense.
