Patent ID: 8784996

Claim:
An extrusion composition comprising from 80% to 98% a multimodal polyethylene and 2% to 20% LDPE wherein the multimodal polyethylene is characterized by: a. M w (abs)/M w (RI)>1.05 and <1.6; b. M z (measured)/ M z (calc)>1.4 and <3.0 where M z (calc) is calculated from the measured I 2 according to M z (calc)=1.5*10 (5.077−0.284*log 10)(I 2 )) ; c. I 2 >8.0 g/10 minutes and <15.0 g/10 minutes; d. CDF(RI fraction)>0.01 at a log 10(M w ) of 5.5; and e. density in the range 0.860-0.965 g/cc; and the LDPE is characterized by having a I 2 less than 10 g/10 minutes and greater than 0.2 g/10 minutes, and a M w (abs)/M w (RI)>2.0.
