Abstract (en)
[origin: WO2022101590A1] The present invention relates to a transparent moulding composition, comprising by weight: (a) from 30 to 90% of at least one (co)polyamide of formula PACMY/Z, in which: PACM represents the bis(4-aminocyclohexyl)-methane made up of at least 30 mol% of trans,trans-bis(4-aminocyclohexyl)-methane relative to the sum of all the isomers of the PACM, Y represents at least one aliphatic dicarboxylic acid, Z represents a repeating unit selected from among a unit obtained from at least one amino acid or a unit obtained from at least one lactam, or a unit XY1 obtained from the polycondensation of at least one aliphatic diamine X and at least one aliphatic dicarboxylic acid Y1, with Z ranging from 0 to 15% by weight in the (co)polyamide PACMY/Z relative to the sum of the constituent elements of the (co)polyamide, (b) from 10 to 70% by weight of at least one semi-crystalline copolyamide of formula A/WS, with A being as defined for Z, W being selected from among 3,3'-dimethyl-4,4'-diamino-dicyclohexylmethane (MACM) and the PACM as defined above, with S being an aromatic dicarboxylic acid, (c) from 0 to 10% of at least one impact modifier selected from among polyether block amides (PEBA) and core-shell polymers, (d) from 0 to 2% by weight of at least one additive, (e) from 0 to 5% by weight of a prepolymer; the sum of the proportions of each constituent element of said composition being equal to 100%, said composition having good alcohol resistance as determined by an ethanol resistance test.
