Abstract:
Disclosed are a composition comprising from 50 to 99.99 weight percent based on the total weight of the composition of a melt-processable thermoplastic polyamide polymer; and a silicon-containing polymeric process additive; wherein the silicon-containing polymeric process additive is present in an amount of from 0.01% to 5.0% by weight based on the total weight of the composition, and an article made from the composition.
Abstract:
Synergists are combined with hyperbranched polyester polyols to form polymer processing additive compositions. The synergists are selected from the group consisting of polyethylene glycols, polyethylene oxides, polycaprolactones and combinations thereof. Compositions containing a thermoplastic polymer and such polymer processing additive compositions, as well as methods of extruding thermoplastic polymers containing such polymer processing additive compositions are also described.
