An additive composition comprises one or more calcium cis-1,2-cyclohexanedicarboxylate salts. The calcium 1,2-cyclohexanedicarboxylate salts have a BET specific surface area of 20 m2/g or more. A method for producing a thermoplastic polymer composition entails mixing the additive composition with a thermoplastic polymer, melting the resulting admixture, and letting the admixture solidify to produce a polymer composition. La présente invention concerne une composition d'additif qui comprend un ou plusieurs sels cis-1,2-cyclohexanedicarboxylate de calcium. Les sels de 1,2-cyclohexane dicarboxylate de calcium ont une surface spécifique BET de 20 m2/g ou plus. Un procédé de production d'une composition de polymère thermoplastique consiste à mélanger la composition d'additif avec un polymère thermoplastique, à faire fondre le mélange ainsi obtenu, et à laisser le mélange se solidifier pour produire une composition de polymère.
