  • Patent number: 5866043
    Abstract: Polymeric compositions are disclosed comprising protonated, electrically conducting polyaniline; cyclic organic compounds capable of forming ring-ring interactions with the six-membered rings of the polyaniline and hydrogen bonding with the NH groups of the polyaniline; and anionic surface active additives. According to the invention, no particular requirements are posed for the counter-ions of polyaniline, which allows for the use of non-functionilized counter-ions. The conducting polyaniline complexes of the invention are processible in the fluid-phase and exhibit significantly improved electrical properties.
    Type: Grant

  • Patent number: 5677394
    Abstract: A melt-processable block copolyesterimide comprising the repeating units (I), (II) and (III) and, optionally, a repeating unit (IV), wherein (I) is a repeating unit of the formula ##STR1## wherein R is an aliphatic polyether chain and/or a polysiloxane chain; (II) and (III) are repeating units of the formulas ##STR2## wherein Z is hydrogen, alkyl, alkoxy, aryl, halogen and w is zero or one; and (IV) is a repeating unit of the formula ##STR3## wherein Z' is hydrogen, alkyl, alkoxy, aryl or halogen and the phenylene ring is substituted in by Z' in the m- or p-positions. The repeating unit of formula (I) is present in an amount of 5 to 50 mole-%, the repeating unit of formula (II) is present in an amount of 10 to 80 mole-%, the repeating unit of formula (III) is present in an mount of 5 to 50 mole-% and the repeating unit of formula (IV) is present in an amount of 0 to 45 mole-% of the block copolyesterimide.
