Abstract: This disclosure relates to ethylene interpolymer compositions, films prepared therefrom and a nonlinear rheology method capable of determining presence of long-chain branched structures in these ethylene interpolymer compositions. Ethylene interpolymer compositions disclosed herein specifically relates to ethylene interpolymer products having: a dimensionless nonlinear rheology network parameter, Δint., greater than or equal to 0.01, satisfying 0.01 × (Z − 48)0.78 ≤∆int.≤ 0.01 × (Z − 60)0.78 inequality wherein Ζ is a normalized molecular weight defined by (I) where Mw and Me are the weight average and entanglement molecular weights; and a residual catalytic metal of from ≥ 0.03 to ≤ 5 ppm of hafnium. 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%.
