Patent ID: 8183328

Claim:
A polymer composition comprising: (a) a grafted and at least partially crosslinked mLLDPE that is the reaction product of: (i) a mLLDPE having a density from 0.910 g/cm 3 to less than 0.940 g/cm 3 and an I 2 from 0.7 dg/min to 5.0 dg/min; (ii) a silicon-containing grafting component; and (iii) a crosslinking agent; and (b) a HDPE having a density from 0.941 g/cm 3 to 0.980 g/cm 3 and an I 22 of 10 dg/min or more, 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.
