  • Antistatic polymer compositions
    Patent number: 6784257
    Abstract: The present invention relates to an antistatic polymer composition and more specifically to a composition comprising a thermoplastic polymer (A) and a copolymer (B) comprising polyamide blocks and polyether blocks comprising essentially ethylene oxide units —(C2H4—O)—, the copolymer (B) having a melting temperature of between 80 and 150° C. It is of use for the polymers (A) which are heat-sensitive or which are processed at low temperature.
    Type: Grant
    Filed: April 24, 2000
    Date of Patent: August 31, 2004
    Assignee: Atofina
    Inventors: Hermann Josef Hilgers, Christophe Lacroix, Reinhard Linemann
