Abstract
The present invention relates to polymer compositions comprising a grafted and at least partially crosslinked mLLDPE that is the reaction product of: (i) a mLLDPE having a density from 0.910 g/cm3 to less than 0.940 g/cm3 and an I2 from 0.7 dg/min to 5.0 dg/min; (ii) a silicon-containing grafting component; and (iii) a crosslinking agent, wherein the composition exhibits a die shrinkage upon extrusion that is at least 10% lower than the composition, prior to grafting and crosslinking of the mLLDPE. These compositions can optionally be blended with HDPE. The compositions can also comprise at least one layer of a film, e.g., made via extrusion.
