    摘要： The present invention relates to a multilayer tubular structure (MLT) for conveying fluids, in particular gasoline, comprising, from the innermost to the outermost layer, at least one inner barrier layer (1) and at least one outer layer (2) located above the barrier layer, said outer layer (2) or the set of layers (2) and of any other layers located above the barrier layer containing on average 0 to 5% of a plasticiser relative to the total weight of the composition of the layer (2), or the set of outer layers located above the barrier layer comprising on average 0 to 5% of a plasticiser, said outer layer (2) predominantly comprising at least one aliphatic polyamide or a polyamide consisting of more than 75% aliphatic units, wherein said aliphatic polyamide is selected from: a polyamide, designated as A, having an average number of carbon atoms per nitrogen atom, designated as C
    A , of 4 to 8.5, advantageously of 4 to 7; a polyamide, designated as B, having an average number of carbon atoms per nitrogen atom, designated as C
    B , of 7 to 10, advantageously of 7.5 to 9.5; a polyamide, designated as C, having an average number of carbon atoms per nitrogen atom, designated as C
    C , of 9 to 18, advantageously of 10 to 18; provided that, when said inner layer (2) comprises at least three polyamides, at least one of the polyamides A, B or C is excluded.

    摘要： The present invention relates to amorphous transparent copolyamides of formula: PACM.T / D.X / X1.Y1 resulting from the condensation of PACM, terephtalic acid, a diamine D, a diacid X, a diamine X1 and a diacid Y1 in which : PACM denotes the p-bis(aminocyclohexyl)methane, T denotes terephtalic acid, D denotes a diamine chosen from aromatic, arylaliphatic and cycloaliphatic diamines, X denotes a diacid HOOC-(CH2)n-COOH having from 8 to 20 carbon atoms, XI denotes an aliphatic diamine, Y1 denotes a diacid HOOC-(CH2)n-COOH having from 6 to 20 carbon atoms, the mol proportion of PACM.T is such as (PACM.T)/(PACM.T+D.X) is above 0.5, and can be increased to 1 , the mol proportion of X1 is between 16% and 38%, X1.Y1 can be replaced partly or totally by Z, a lactam or an alpha-omega aminocarboxylic acid, having from 9 to 20 carbon atoms, and in this case the mol proportion of Z is between 33% and 75%.
