Abstract:
A catalyst comprising units of the formula: where each R is independently hydrogen, C1-6 alkyl, or C6-14 aryl; where each Râ€² is independently R, C1-6 alkoxy, C7-20 alkaryl, C7-20 aralkyl, halogen, or CF3; where M is a Group 3 to 10 metal; where each X is independently halogen, C1-6 alkyl, C6-14 aryl, C7-20 alkaryl, C7-20 aralkyl, C1-6 alkoxy, or â€ƒL is X, cyclopentadienyl, C1-6 alkyl-substituted cyclopentadienyl, fluorenyl, indenyl, or â€ƒwhere n is an integer from 1 to 4; a is an integer from 1 to 3; b is an integer from 0 to 2; the sum of a+b&lE;3; c is an integer from 1 to 6; and the sum a+b+c equals the oxidation state of M.
