Abstract
A process for melt-spinning a synthetic linear fiber-forming polymer into filaments by extrusion through a nozzle or so-called nozzle plate treated on its discharge face with a thin layer silicone oil coating wherein said coating is stabilized with a cerium compound. The stabilizing composition or additive preferably consists essentially of the reaction product of a cerium compound with a polymethylsiloxane bearing reactive hydrogen atoms.
