Patent ID: 8653196

Claim:
A method for increasing the melt strength of a polyethylene resin comprising the steps of: a. selecting a polyethylene resin having a density, as determined according to ASTM D792, in the range of from 0.865 g/cm 3 to 0.962 g/cm 3 , and a melt index, as determined according to ASTM D1238 (2.16 kg, 190° C.), in the range of from 0.01 g/10min to 100 g/10 min, wherein the polyethylene resin is selected from the group consisting of high density polyethylene (HDPE), linear low density polyethylene (LLDPE) and blends thereof; b. reacting an alkoxy amine derivative with the polyethylene resin in an amount and under conditions sufficient to increase the melt strength of the polyethylene resin, wherein the alkoxy amine derivative is added to the polyethylene resin as a masterbatch comprising the alkoxy amine derivative along with a carrier resin comprising LDPE.
