Definitions

  • the maleic anhydride grafted ethylene/1 -hexene interpolymer (mal- LLDPE herein) was then prepared utilizing a 40-mm x 55-L/D (length/ diameter) Berstorff ZE 40A twin screw extruder, produced and sold by Berstorff Corporation, of Florence, Kentucky.
  • the extruder screw speed was set at 270 rpm.
  • Pellets of the ethylene/1 -hexene interpolymer having a density of 0.917 g/cc, a melt index of 0.8 dg/min, and a Melt Flow Ratio of 27, were fed to the feed throat of the extruder by a volumetric pellet feeder at a rate of 45 kg/h, and the pellets were melted in barrels 1 and 2.
  • Maleic anhydride was injected at a rate of 1.1 kg/h through an injection device located between barrels 2 and 3 of the extruder.
  • the maleic anhydride was then mixed with the interpolymer in three sequential reaction/mixing zones, each separated from the other by reverse conveying elements. The three sequential mixing/reaction zones were maintained at a temperature of 358°C.
  • compositions of Table 2 that were formed into films were measured for yellowness index prior to being formed into films.
  • the yellowness index values are reported below in table 3.
