Random ethylene/alpha-olefin/diene monomer interpolymers with an alpha-olefin distribution that is more clustered than Bernoullian are prepared using Group 4 metal constrained geometry complex catalyst and an activating cocatalyst. The catalyst includes a fused ring indenyl derivative ligand.
L'invention concerne des interpolymères statistiques de monomères d'éthylène/alpha-oléfine/diene qui présentent une distribution alpha-oléfinique plus groupée que celle de Bernoulli et sont préparés à l'aide d'un catalyseur d'un complexe de métaux du groupe 4 à géométrie contrainte et d'un cocatalyseur d'activation. Le catalyseur renferme un ligand dérivé indénylique à anneaux condensés.
