  • Patent number: 10605385
    Abstract: The invention relates to the use of a layer consisting of a composition comprising a copolyamide of formula X/10.T/Y for transporting a heat transfer fluid in a vapor compression circuit, wherein: X represents either the residues of an aliphatic amino acid comprising between 8 and 18 carbon atoms, or a lactam, or the unit X1.X2 representing the residues resulting from the condensation of an aliphatic diamine comprising between 6 and 18 carbon atoms and a (cyclo)aliphatic diacid comprising between 6 and 18 carbon atoms; 10.T represents the residues resulting from the condensation of a decanediamine and terephthalic acid; and Y represents the residues resulting from the condensation of an aliphatic diamine comprising between 9 and 14 carbon atoms and an aromatic diacid, Y being different from the unit 10.T; the molar proportion of 10.T units being higher than 0%.

  • Patent number: 9914804
    Abstract: The invention relates to a method for synthesising a block copolymer alloy including at least one rigid polyamide block PA, including the steps of: a) producing said block copolymer; b) adding, during step a) and to at least a portion of said block copolymer, 0.1 to 30 wt % of at least one organic salt in the molten state relative to the total weight of the alloy, so that the alloy thus obtained has improved antistatic properties and identical mechanical properties when compared to the same polymer produced without adding an organic salt. The invention also relates to a block copolymer alloy having improved antistatic properties and obtained by said method, to the use thereof in a polymer matrix, and to a composition containing same.
