Abstract
An ethylene polymer having PA1 a) a Polydispersity Index, PDI, of about 3 to 9; PA1 b) an nRSI of about 5 to about 18; PA1 c) a cRSI of about 1.1 to 3.0; PA1 d) a Composition Distribution Index, CDI(100), greater than about 45; and PA1 e) a log-viscosity ratio, log(.eta.0/[.eta.]), of about 0.5 to about 1.5 is described. The ethylene polymer has improved processability over conventional linear low density polyethylene.
