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≤Δint.≤0.01×(Z−60)0.78 inequality wherein Z is a normalized molecular weight defined byZ=MwMewhere 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%.
