1,9-Decadiene/propylene copolymers were obtained with isolated metallocenes and with a binary metallocene catalyst system activated by methylaluminoxane. The metallocenes under investigation were syndiospecific diphenylmethyl(cyclopentadienyl)(9-fluorenyl)zirconium dichloride (1) and isospecific rac-dimethylsilylbis(4-tert-butyl-2-methyl-cyclopentadienyl)zirconium dichloride (2). A copolymer structure,...
Commercial methylaluminoxane (MAO) solutions were dried under reduced pressure to remove trimethylaluminium (TMA) and solvent. TMA has been added to a solution of such dried MAO, and the response was followed by a special in situ FTIR spectroscopic technique. No reaction was seen between TMA and MAO in toluene solution at room temperature within a time span of up to 4h TMA and MAO remained in the...
