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.

摘要： Melt processed linear polyethylenes containing an amine additive are shown to exhibit improved processability through the addition of certain surfactants. The amine compounds are generally one or more hindered amine light stabilizers (HALS), amine antistats, amine antioxidants or amine based UV inhibitors. 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 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 a quaternary ammonium cations, said surfactant being essentially free of halogens.

摘要： Disclosed are (1) a thermoplastic elastomeric film comprised of an elastomeric arene-diene block copolymer and particular ethylene/&bgr;-olefin copolymers having low ethylene crystallinity and (2) the process of preparing films thereof. The disclosed films have superior strength and elasticity characteristics which render them particularly useful in apparel and healthcare items such as disposable diapers.
