摘要：
Addition polymerization catalysts having a limiting charge separated structure corresponding to the formula:
LMX⁺ XA⁻,
wherein:
L is a derivative of a substituted delocalized Π-bonded group imparting a constrained geometry to the metal active site and containing up to 50 nonhydrogen atoms;
M is a metal of Group 4 or the Lanthanide series of the Periodic Table of the Elements;
X independently each occurrence is hydride or a hydrocarbyl, silyl or germyl group having up to 20 carbon, silicon or germanium atoms; and
A⁻ is an anion of a Lewis acid, A, having relative Lewis acidity greater than or equal to that of phenylbis(perfluorophenyl)borane, said anion being compatible with the metal cation,
are prepared by contacting a derivative of a Group 4 or Lanthanide metal corresponding to the formula:
LMX₂,
wherein
L, M, and X are as previously defined,
with the Lewis acid, A.
