摘要： The invention relates to a method of increasing the molecular mass of a polycondensate in solution, wherein polycondensate is reacted with at least one chain extender out of the group consisting of bislactams, cyclic amino ethers, siloxanes and thiols. The invention further relates to a high molecular mass polycondensate in solution, wherein the polycondensate has an intrinsic viscosity as measured in hexafluoroisopropanol of at least 0.9 dl/g and a molecular mass distribution (Mw/Mn) of less than (2). The invention further relates to a process for producing a filament or film of a polycondensate comprising forming a solution of polycondensate by the method according to the invention, extruding the solution through a spinneret or a slot die, through air and into a cooling bath to form a gel filament or film, optionally removing residual solvent from the filament or film and drawing the filament or film at least (15), preferably at least (25) times. The invention further relates to shaped articles obtainable by the process thereof.
