Abstract
A thermoplastic polymer composition comprises a thermoplastic polymer, at least one clarifying agent, and at least one coloring agent. A method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer and an additive composition and then mixing the thermoplastic polymer and additive composition. The additive composition comprises a clarifying agent and a coloring agent. Another method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer, at least one clarifying agent, and at least one coloring agent and then mixing the thermoplastic polymer, the clarifying agent, and the coloring agent. The thermoplastic polymer exhibits a blue hue factor (α) of 0.93 to 1.1 and/or a normalized brightness value (Y') of 64.0 to 69.6. An additive composition contains at least one clarifying agent and at least one coloring agent.
