摘要：A polymer processing additive (PPA) composition to improve melt extrusion ofan extruded composition comprising an extruded thermoplastic polymer, the PPAcomposition comprising of at least one fluoropolymer having a Mooney viscosity (ML1+10 @ 121°C) of about 30 to about 90 (ASTM D 1646-06 Part A with an MV 2000instrument (available from Alpha Technologies, Ohio) using a large rotor (ML 1+10) at121°С) and at least one polydiorganosiloxane polymer, wherein said extruded
thermoplastic polymer is selected from a polypropylene homopolymer, a polypropylenecopolymer, and a combination thereof. Also provided is a method for extruding polymersusing the PPA compositions, as well as extruded products comprising the PPAcomposition.
