Abstract (en)
[origin: WO9849212A1] 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.
