  • Antistatic compositions based on polyamide
    Patent number: 6506830
    Abstract: This antistatic polyamide composition, comprising at least one polyamide and a sufficient amount of carbon black to make it antistatic, is characterized by the fact that the carbon black is at least a carbon black that is selected from among those having a specific BET surface area, measured according to ASTM Standard D 3037-89, from 5 to 200 m2/g, and DBP absorption, measured according to ASTM Standard D 2414-90, from 50 to 300 ml/100 g.
    Type: Grant
    Filed: October 6, 2000
    Date of Patent: January 14, 2003
    Assignee: Atofina
    Inventors: Philippe Bussi, Frédérique Pery, Jacques Thomasset
  • Flexible thermoplastic resins having improved tensile strength
    Patent number: 6281287
    Abstract: The invention relates to a thermoplastic composition comprising at least one polymer (M) forming a matrix in which are dispersed at least one polymer (S) and at least one polymer (K) and such that its tensile strength is greater than that of a composition comprising only (M) and (S), the proportion by weight of (M) being the same.
    Type: Grant
    Filed: June 26, 2000
    Date of Patent: August 28, 2001
    Assignee: Atofina
    Inventors: Thibaut Montanari, Chrystelle Guibouin, Marius Hert, Patrice Perret, Jacques Thomasset, Didier Roumilhac
  • Thermoplastics with improved flexibility and transparency
    Patent number: 6239216
    Abstract: The invention relates to a thermoplastic composition comprising at least one polymer (M) forming a matrix in which are dispersed nodules of (K), nodules of (K) entirely or partly encapsulated in at least one polymer (S) and nodules of (S) and such that the nodules of (K) entirely or partly encapsulated in (S) are smaller than the nodules of (S).
    Type: Grant
    Filed: August 27, 1998
    Date of Patent: May 29, 2001
    Assignee: Atofina
    Inventors: Thibaut Montanari, Chrystelle Guibouin, Marius Hert, Patrice Perret, Jacques Thomasset
  • Multiphase thermoplastic resin compositions
    Patent number: 6127456
    Abstract: The invention relates to a thermoplastic composition comprising at least one polymer (M) forming a matrix in which are dispersed nodules of at least one polymer (K) which are encapsulated in at least one polymer (S) in such a way that these encapsulated nodules are smaller than the nodules of the polymer (S) which are dispersed in the matrix (M).
