Catalytic Polymerization of Butadiene in Aqueous Systems with Cationic Nickel(II) Complexes
The cationic nickel(II) complexes [(η-C3H5)Ni(SbPh3)2][B(3,5-(CF3)2C6H3)4] (2) and [(η3C3H5)Ni(SbPh3)2][Al(OC(CF3)3)4] (3) were prepared and their polymerization activities in aqueous systems were compared with [(η-C3H5)Ni(η-BHT)][B(3,5-(CF3)2C6H3)4] (1) (BHT ) 3,5-di-tert-butyl-4-hydroxytoluene). Cispolybutadiene is formed in nonaqueous solution polymerization. The presence of water decreases ...
متن کامل(η4-s-cis-1,3-Butadiene)tetracarbonylchromium(0)
In the title complex, [Cr(C(4)H(6))(CO)(4)], the Cr(0) atom shows a distorted octa-hedral environment from four C atoms of the carbonyl ligands and the two π-bonds of the s-cis-1,3-butadiene ligand. The complex has an approximate non-crystallographic mirror symmetry m passing through the chromium atom, two carbonyl ligands and the mid-point of the central C-C bond of the s-cis-1,3-butadiene lig...
متن کاملSynthesis of neutral nickel catalysts for ethylene polymerization--the influence of ligand size on catalyst stability.
A facile synthesis of nickel salicylaldimine complexes with labile dissociating ligands is described. In addition to producing highly active ethylene polymerization catalysts, important insights into the effect of ligand size on catalyst stability and information on the mechanism of polymerization are provided.
متن کاملPreparation of cassava starch grafted with polystyrene by suspension polymerization.
Cassava starch grafted with polystyrene (PS-g-starch) copolymer was synthesized via free-radical polymerization of styrene by using suspension polymerization technique. Potassium persulfate (PPS) was used as an initiator and water was used as a medium. The graft copolymer was characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermal gravimetric analysi...
متن کاملPolymerization 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...
