Polymerization of epoxides with dialkylaluminum acetylacetonate catalyst systems

Polymerization of Propylene with [t-BuNSiMe2Ind]TiMe2-MAO Catalyst Systems

ansa-Indenylamidodimethyltitanium complex ([t-BuNSiMe2Ind]TiMe2: 1) was synthesized by one-pot reactions starting from the ligand, MeLi and TiCl4. The structure of 1 was determined by X-ray crystallography and the results obtained revealed that the indenyl ligand coordinate to titanium in an η-tendency. Propylene polymerization was conducted with 1 in toluene or heptane as solvent at 0 ̊C in th...

Mechanism of Initiation of Polymerization by Ferric Acetylacetonate

Results on the autooxidative decomposition of the transition metal B-diketonates (1-3) suggested the possibility of these chelates acting as initiators for the radical polymerization of vinyl monomers. Research in this field soon revealed the importance of the central metal atom as well as the ligand structure (4-10). Of a series of metal acetylacetonate~-Mn(Acac)~, M n ( A ~ a c ) ~ , Fe( A ~ ...

Regio-controlled ring-opening polymerization of perfluoroalkyl-substituted epoxides.

Highly fluorinated epoxides were polymerized under mild conditions regioregularly, which gave easy access to isotactic polymers by using optically pure epoxides.

A New Homogeneous Catalyst for the Dehydrogenation of Dimethylamine Borane Starting with Ruthenium(III) Acetylacetonate

Polymerization catalyst laser-interference patterning.

The binding of molecular polymerization catalysts to solid supports, in the form of microporous particles or also flat substrates, has been extensively studied. 11 .] The primary aim is to gain control of the morphology of the polymer formed directly during polymerization. This approach can be convenient, for example, in saving additional processing steps if the polymer is formed directly in th...
