Abstract:
This disclosure relates to ethylene interpolymer compositions and films prepared therefrom. Specifically: ethylene interpolymer products having: a dimensionless nonlinear rheology network parameter, Δint., greater than or equal to 0.01, satisfying 0.01×(Z−50)0.78≤Δint.≤0.01×(Z−60)0.78 inequality wherein Z is a normalized molecular weight defined by Z = M w M e 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, M w M n , from about 1.7 to about 25 and a Composition Distribution Breadth Index (CDBI50) from about 1% to about 98%.
