  • Thermoplastic elastomers
    Patent number: 6300463
    Abstract: Thermoplastic elastomeric polymers which contain polyether blocks having tetramethylene ether repeat units, and polyamide blocks, have improved elastomeric properties such as higher unload power and lower tensile set, when the polyether blocks also contain 2-alkyltetramethylene ether repeat units. The polymers are useful as molding resins and for fibers.

    Inventors: Garret Daniel Figuly, Marc Bruce Goldfinger
  • Crosslinked polymeric ammonium salts
    Patent number: 5874522
    Abstract: Disclosed are novel crosslinked polymeric ammonium salts wherein in said polymeric salt: about 25% or more of the segments which link ammonium nitrogen atoms are group Y wherein Y is an n-alkylene group or alkyl substituted n-alkylene group, wherein said n-alkylene group has 7 to about 20 carbon atoms; zero to about 75% of segments which link ammonium nitrogen atoms are group Z wherein Z is a hydrocarbylene radical containing 2 or more carbon atoms, said hydrocarbylene radical optionally containing one or more hydroxyl, ether, amino, thioether, keto, or silyl groups or heterocyclic rings; and about 25% or more of the ammonium atoms are secondary ammonium atoms.
