  • Color Reduction in Polyethylene Modified by Radical Initiation
    Publication number: 20100081746
    Abstract: Polyethylene modified by using radical initiators such as oxygen and peroxides sometimes has a yellow color which may be reduced or eliminated by incorporating additives such as polyethylene glycol, and/or neutralizing species such as alkali metal stearates, particularly calcium stearate, and zinc oxide.
    Type: Application

  • Methods for controlling polyethylene rheology
    Publication number: 20070007680
    Abstract: The rheology of polyethylene resin may be controlled by measuring the specific energy input (SEI) to the extruder and then adjusting a process parameter in response to a change in the SEI and/or by introducing both a free radical initiator and an alkali earth metal stearate into the polymerization. Indeed, the process parameter changed in response to the SEI measurement may be adjusting the proportion of free radical initiator, adjusting the proportion of alkali earth metal stearate, or both. The free radical initiator may be a peroxide, and the alkali earth metal stearate may be calcium stearate.

  • Polyethylene useful for blown films and blow molding
    Patent number: 7081285
    Abstract: Blown films and blow molded objects may be prepared using a polyethylene composition comprising a unimodal metallocene catalyzed polyethylene copolymer. The polyethylene copolymer has high melt fow rate and good melt strength allowing it to be useful in both extrusion and injection blow molding. Blown film prepared therewith has a high level of clarity.
