<p>A composition useful as an addition polymerization catalyst comprising: (a) an inert support; (b) a Group 3-10 or Lanthanide metal complex; and (c) an activator compound capable of causing the metal complex B to form an active polymerization catalyst, said compound corresponding to the formula (I): (A*+a)b(Z*J*j)-cd, wherein A* is a cation of charge +a, Z* is an anion group of from 1 to 50, preferably 1 to 30 atoms, not counting hydrogen atoms, further containing two or more Lewis base sites; J* independently each occurrence is a Lewis acid coordinated to at least one Lewis base site of Z*, and optionally two or more such J* groups may be joined together in a moiety having multiple Lewis acidic functionality, j is a number from 2 to 12 and a, b, c, and d are integers from 1 to 3, with the proviso that a x b is equal to c x d.</p> |
