BLOCK COPOLYMER POLYMER PROCESSING AIDS

A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a block copolymer having polyamide blocks and polyether blocks and reduces melt defects well in a thermoplastic polyolefin such as a linear low density p...

More Information
Summary:A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a block copolymer having polyamide blocks and polyether blocks and reduces melt defects well in a thermoplastic polyolefin such as a linear low density polyethylene (LLDPE). Un auxiliaire de traitement de polymère (PPA) réduit les irrégularités de fusion dans des polyoléfines extrudées en l'absence de fluoropolymères. L'auxiliaire de traitement de polymère comprend un copolymère séquencé ayant des blocs polyamide et des blocs polyéther et réduit les irrégularités de fusion dans une polyoléfine thermoplastique telle qu'un polyéthylène basse densité linéaire (LLDPE).
