Method of processing polyethylene and polyethylene/elastomer blends |
摘要 |
Melt processed linear polyethylenes which may optionally contain an elastomer, are shown to exhibit improved processability through the addition of certain surfactants. Among the melt processing parameters improved are reduced head pressure, reduced torque, reduced motor load, reduced or eliminated melt fracture, or combinations of these parameters. The surfactants can be chosen from a non-aromatic alkyl sulfonate or sulfate salt wherein a cation of the salt is selected from the group consisting of Na, K, Li, and other alkali cations and quaternary ammonium cations, said surfactant being essentially free of halogens.
