  • non-coordinating anion type activators comprising an indolinium moiety, preferably an alkyl substituted indolinium moiety.
  • Polyolefins are widely used commercially because of their robust physical properties. Polyolefins are typically prepared with a catalyst that polymerizes olefin monomers. Therefore, there is interest in finding new catalysts and catalyst systems that provide polymers having improved properties.
  • Catalysts for olefin polymerization are often based on metallocenes as catalyst precursors, which are activated either with an alumoxane or an activator containing a non coordinating anion.
  • a non-coordinating anion such as tetrakis(pentafluorophenyl)borate, is capable of stabilizing the resulting metal cation of the catalyst.

  • Solubility Study of the activators The solubility of the activators is summarized in Table 3. The solubility was determined using a saturated solution of the activator prepared by slowly adding the solvent to a pre-weighed amount of the activator. The final volume was determined as the minimum amount of solvent required to convert the heterogenous mixture into a homogeneous solution. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM). Alternatively, a mixture of the activator was prepared by adding the solvent to an excess amount of activator. The resulting slurry was separated from the undissolved solids by decanting the mixture into a tared vial. Solvent was then added dropwise until the mixture became a homogeneous solution. The mass of the final solution was measured and then the solvent was evaporated to dryness to obtain the mass of the activator. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM).
