Abstract
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=(SC−T)/T, where SCis the amount of a side chain unsaturation per 100 carbons and Tis 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 (M/M) from about 1.7 to about 25 and a Composition Distribution Breadth Index (CDBI) from about 1% to about 98%.
