A poly(oxyalkylene) polymer and a metal salt of a carboxylic acid, sulfonic acid, or alkylsulfate, in combination are useful as a polymer processing additive synergist. Polymer processing additive compositions, homogeneously catalyzed olefin compositions, and other extrudable polymer compositions including a poly(oxyalkylene) polymer and a metal salt of a carboxylic acid, sulfonic acid, or alkylsulfate are disclosed. Methods of reducing melt defects during the extrusion of a thermoplastic polymer, which may be a homogeneously catalyzed polyolefin, are also disclosed.

Polymer processing additive, compositions, and methods

A composition includes a thermoplastic fluoropolymer having vinylidene fluoride units in an amount of at least 30 mole percent and tetrafluoroethylene units in an amount of at least 5 mole percent. The thermoplastic fluoropolymer is free of hexafluoropropylene units or comprises less than 5 mole percent hexafluoropropylene units. The composition further includes at least one of a non-fluorinated, thermoplastic polymer as a major component of the composition or a polymer processing additive synergist. A method of reducing melt defects during the extrusion of a polymer is also provided. Use of the thermoplastic fluoropolymer as a polymer processing additive is also provided.
