Abstract
The invention relates to a process for producing a shaped article having excellent mechanical properties, said article comprising a block copolymer PAX.Y/PE comprising polyamide (PA) blocks alternating with polyether (PE) blocks, prepared from homopolyamide blocks PAX.Y by polycondenstation of linear aliphatic diamines where PAX.Y is selected from the group consisting of PA 10,12; PA 6,18; PA 10,14; and PA 12.12, reacted with polyether PE blocks in the presence of a catalyst to produce a block copolymer PAX.Y/PE, wherein said PE blocks are either PE diols, or PE blocks comprising NHends. The articles formed are either a fabric, film, sheet, rod, pipe, injection-molded component, or a shoe sole; the copolymer PAX.Y/PE has an improved flexural modulus of at least 300 MPa greater than a copolymer polyamide 12/polytetrametylene with the same size of PA block and with the same size of PE block respectively.
