  • Blends of nylon M5T and an ionomer
    Patent number: 5200468
    Abstract: Polymer compositions are provided which are capable of being formed into shaped articles and comprise a poly(2-methylpentamethylene terephthalamide), also known as nylon M5T, and a minor amount of an ionomer, e.g., a partially neutralized copolymer of an alpha-olefin and an alpha, beta-ethylenically unsaturated carboxylic acid. In particular, the compositions may be melt spun and drawn into filaments having good mechanical properties.

  • Process for spinning preceramic polymers
    Patent number: 5093062
    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.
