ABSTRACT:
Organometallic preceramic polymers are melt spun into fibers utilizing a spinning apparatus which directs the preceramic polymer from a stagnant melt pool of said polymer to a spinneret. The spinneret is one used for solvent spinning and, thus, has a shorter residence time during extrusion through the spinneret orifice than conventional melt spinning spinnerets.
