An additive composition comprises a liquid medium and a clarifying agent. The liquid medium is either a liquid hydrocarbon or a surfactant having an HLB of about 6 or less. The clarifying agent is dispersed in the liquid medium. In certain particular embodiments, the additive composition comprises both the liquid hydrocarbon and the surfactant, with the liquid hydrocarbon providing the medium for the additive composition. A thermoplastic polymer composition comprises a thermoplastic polymer and an additive composition of the invention. A method for producing a thermoplastic polymer composition comprises the steps of providing a thermoplastic polymer, providing an additive composition, and mixing the thermoplastic polymer and the additive composition to produce the thermoplastic polymer composition. |
