This disclosure relates to ethylene interpolymer compositions and films prepared therefrom. Specifically: ethylene interpolymer products having: a dimensionless Long Chain Branching Factor, LCBF, greater than or equal to 0.001; a residual catalytic metal of from > 0.03 to < 5 ppm of hafnium, and; a dimensionless unsaturation ratio, UR, of from > -0.40 to < 0.06, wherein UR is defined by the following relationship; UR = (SCU-TU)/TU, where SCU is the amount of a side chain unsaturation per 100 carbons and TU is amount of a terminal unsaturation per 100 carbons, in said ethylene interpolymer product. The disclosed ethylene interpolymer products have a melt index from about 0.3 to about 500 dg/minute, a density from about 0.855 to about 0.975 g/cc, a polydispersity (Mw/Mn) from about 1.7 to about 25 and a Composition Distribution Breadth Index (CDBI50) from about 1 % to about 98%. |
