Abstract
An additive composition comprises one or more calcium cis-1,2-cyclohexanedicarboxylate salts. 25 mol. % or more of the calcium cis-1,2-cyclohexanedicarboxylate salts present in the additive composition are calcium cis-1,2-cyclohexanedicarboxylate monohydrate. The additive composition has a gravimetric water content of about 20% or less. 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.
