The present disclosure relates to ethylene interpolymer compositions and films made therefrom. Specifically: an ethylene interpolymer product having: a dimensionless long chain branching factor LCBF greater than or equal to 0.001; a residual catalytic metal of >0.03 to <5 ppm hafnium; and a dimensionless >‑0.40 to <0.06 Unsaturation ratio UR, where UR is defined by the following relationship; UR=(SC U- TU )/TU , where SC U is the degree of side chain unsaturation per 100 carbons in the ethylene interpolymer product and TU is the amount of terminal unsaturation per 100 carbons in the ethylene interpolymer product. The disclosed ethylene interpolymer products have a melt index of about 0.3 to about 500 dg/min, a density of about 0.855 to about 0.975 g/cc, a polydispersity (Mw/Mn) of about 1.7 to about 25, and a polydispersity ( Mw / Mn ) of about 1.7 to about 25. % to about 98% Composition Distribution Breadth Index ( CDBI50 ). |
