    • A polymer composition comprising: at least one polycondensation polymer having a heat deflection temperature (HDT) of above 80° C. under a load of 1.82 MPa when measured according to ASTM D648 [polymer (P)]; at least one perfluoropolyether block copolymer [polymer (F)] comprising: A) one or more (per)fluoropolyoxyalkylene segment (chain Rf) comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and B) one or more polyalkylene segment (chain Ra) comprising recurring units of formula: —(CR1R2—CR3R4)—; wherein R1, R2, R3, R4, equal to or different from each other, are selected from the group consisting of H, halogens; C1-C6 (hydro)carbon groups, optionally containing fluorine or other heteroatoms, to a process for its manufacture and to its use for manufacturing shaped articles, in particular by extrusion molding or injection molding techniques.
