ABSTRACT:
A process for preparing filaments of polyketones which can be formed into various fibers is presented. The process involves preparing a solution of polyketone in a solvent, passing the solution through a die to produce a strand, coagulating the strand to produce a filament, removing solvent from the presence of the filament, and subsequently drawing the filament. The solvents are zinc and lithium based solutions.
