FIELD: chemistry.

SUBSTANCE: polymer composition comprises, at least, one polyamide and, at least, one compound of the formula , in which x is 1, 2 or 3; R¹ and R²are independently selected from hydrogen, linear C₁-C₇-alkyl, branched C₃-C₁₀-alkyl, unsubstituted or substituted C₃-C₁₂-cycloalkyl, unsubstituted or substituted C₃-C₁₂cycloalkyl-C₁-C₄-alkyl, unsubstituted or substituted aryl and unsubstituted or substituted aryl-C₁-C₄-alkyl; and Z is trans 1,4-cyclohexanediyl. The use of a compound of formula I in a polymer composition for improving, at least, one optical property selected from increased transparency, increased laser transparency and reduced turbidity, and a moulded article produced from the said composition are also described.

EFFECT: providing improved optical properties selected from reduced turbidity, improved transparency and improved laser transparency in polyamide compositions using the compound of formula I.
