    摘要: A poly(oxyalkylene) polymer having a weight average molecular weight of at least 50,000 grams per mole and a metal salt of a carboxylic acid, sulfonic acid, or alkylsulfate, in combination are useful as a polymer processing additive. In some embodiments, the polymer processing additive further includes a poly(oxyalkylene) polymer having a weight average molecular weight of up to 20,000 grams per mole Polymer processing additive compositions and thermoplastic, for example, polyolefin, 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.

    摘要: A composition includes a first amorphous fluoropolymer having a first Mooney viscosity ML 1+10 @ 121° C. less than 60 and a second amorphous fluoropolymer having a second Mooney viscosity ML 1+10 @ 121° C. greater than 80. 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 a combination of the first and second amorphous fluoropolymers as a polymer processing additive is also provided.
