Abstract
An additive composition comprises a plurality of granules. The granules comprise a polymer additive selected from the group consisting of clarifying agents, nucleating agents, and mixtures thereof. About 75 wt. % or more of the granules present in the additive composition have a particle size of about 0.5 mm to about 2.8 mm, and the granules have a particle hardness of less than 50 cN. A method for producing a polymer composition utilizes the above-described additive composition.
