Polymer Processing Aids For Polymer Extrusion
Abstract: The present invention relates to a thermoplastic polymer composition comprising a matrix polymer (A) and a polymer processing aid (B), wherein: - (d polymer (B) – d matrix polymer (A)) >=2.0 (J1/2.cm-3/2), preferably > 3.0 (J1/2.cm-3/2), d being the solubility parameter calculated according to Fedor method, and - the melt viscosity ratio of polymer (B) over matrix polymer (A) is less than 0.30, preferably less than 0.20, the melt viscosity being measured by capillary rheometry at 210°C and a shear rate of 100 s-1.
