Polymerization of styrene using catalytic systems based on nickel derivatives and methylaluminoxane (MAO) was studied. Among tested catalysts, nickel bis-(acetylacetonate) and nickel dichloride show the maximum activity. Bis(phosphine)nickel dichlorides exhibit lower activity, depending on the natur
A new diphosphinoamine ligand [Ph 2 PN(p-C 6 H 4 OMe)PPh 2 ] was prepared through aminolysis reaction of p-methoxyaniline with Ph 2 PCl in the presence of NEt 3 . Consequently, the corresponding nickel (II) diphosphinoamine complex [(p-C 6 H 4 OMe)N(PPh 2 ) 2 NiCl 2 ] was synthesized and characteriz
## Abstract The polymerization of norbornene (NBE) was investigated in the presence of two novel pyrazolylimine nickel complexes [2β(C~3~HN~2~Me~2~β3,5){C(Ph)ο£Ύ[4βR~2~C~6~H~2~(R~1~)~2~β2,6]}NiBr~2~ (complex 1, R~1~ = ^i^Pr and R~2~ = H; complex 2, R~1~ = H and R~2~ = NO~2~)] activated by methylalumi
## Abstract The polymerization of methyl methacrylate (MMA) was investigated using a series of bis(Ξ²βketoamino)nickel(II) complexes in combination with methylaluminoxane in toluene solution. The binary catalyst is necessary for initiating MMA polymerization and producing PMMA with high molecular we
