Abstract
This disclosure relates to ethylene interpolymer compositions. Specifically, ethylene interpolymer products having: a Dilution Index (Yd) greater than 0; total catalytic metal≧3.0 ppm; ≧0.03 terminal vinyl unsaturations per 100 carbon atoms, and; optionally a Dimensionless Modulus (Xd) greater than 0. The disclosed ethylene interpolymer products have a melt index from about 0.3 to about 500 dg/minute, a density from about 0.869 to about 0.975 g/cm3, a polydispersity (Mw/Mn) from about 2 to about 25 and a CDBI50 from about 20% to about 97%. Further, the ethylene interpolymer products are a blend of at least two ethylene interpolymers; where one ethylene interpolymer is produced with a single-site catalyst formulation and at least one ethylene interpolymer is produced with a heterogeneous catalyst formulation.
