Abstract
Official abstract text for this publication.
A polymeric composition includes an ethylene-based polymer and a free radical scavenger having structure (I), wherein, R1 and R2 are independently linear, or branch form alkyl, alkenyl, phenyl or aryl group moieties with or without substituents and each of R1 and R2 have a carbon number from 1 to 100, further wherein the polymeric composition is thermoplastic.
First claim
Opening claim text (preview).
1 . A polymeric composition comprising: an ethylene-based polymer; and a free radical scavenger having structure (I), wherein, R 1 and R 2 are independently linear, or branch form alkyl, alkenyl, phenyl or aryl group moieties with or without substituents and each of R 1 and R 2 have a carbon number from 1 to 100, further wherein the polymeric composition is thermoplastic. 2 . The polymeric composition of claim 1 , wherein the polymeric composition is free of carbon black. 3 . The polymeric composition of claim 2 , further comprising a colorant. 4 . The polymeric composition of claim 1 , wherein the ethylene-based polymer comprises a linear low-density polyethylene having a density of 0.917 g/cc to 0.926 g/cc as measured according to ASTM D792 and a high-density polyethylene having a density of 0.940 g/cc to 0.970 g/cc as measured according to ASTM D792. 5 . The polymeric composition of claim 4 , wherein the polymeric composition comprises 80 wt % to 95 wt % high-density polyethylene based on the total weight of the polymeric composition. 6 . The polymeric composition of claim 5 , wherein the polymeric composition comprises 5 wt % to 20 wt % of the linear low-density polyethylene based on the total weight of the polymeric composition. 7 . The polymeric composition of claim 1 , wherein the free radical scavenger comprises alpha-methyl styrene dimer. 8 . The polymeric composition of claim 1 , wherein the free radical scavenger comprises diphenyl ethylene. 9 . The polymeric composition of claim 1 , wherein the polymeric composition comprises from 0.1 wt % to 1.0 wt % of the free radical scavenger based on a total weight of the polymeric composition. 10 . A coated conductor comprising: a conductor; and the polymeric composition of claim 1 disposed at least partially around the conductor.
