FIELD: polymers.
SUBSTANCE: invention relates to compositions containing a polymeric additive. The additive composition contains many granules. The granules contain a polymeric 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 0.5 mm to 2.8 mm, and the granules have particle strength of 2 cN to 50 cN. The method for producing the polymer composition uses the additive composition described above.
EFFECT: invention provides increased fluidity without adversely affecting the optical properties of the polymer.
