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 R f ) comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and B) one or more polyalkylene segment (chain R a ) comprising recurring units of formula: —(CR 1 R 2 —CR 3 R 4 )—; wherein R 1 , R 2 , R 3 , R 4 , equal to or different from each other, are selected from the group consisting of H, halogens; C 1 -C 6 (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. |
