    Abstract: Clarified polyolefins such as polypropylene are used widely to make polymer articles, containers, and the like. Such articles may be manufactured by the injection of molten polymer into a mold or forming device in manufacturing processes at high rates. A clarified composition is provided to achieve optimized clarity and organoleptic performance at lower processing temperatures and/or within a polypropylene resin having a higher melt flow rate.

    Abstract: 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.

    Abstract: Diacetals of sorbitols and xylitols are employed in polyolefins as nucleating agents. Diacetals of sorbitols and xylitol nucleating agents may be provided in granular or powder form from hoppers or mixing equipment into polyolefins during the formation of polymeric compositions and polymeric articles. Flow of diacetals of sorbitols and xylitols is improved by the use of certain silicas, in certain defined weight percentages. Submicron size range silica compounds may provide excellent flow enhancement properties when blended and used with diacetals of sorbitols and xylitols powder compounds. A hydrophobic silica mixed with diacetals of sorbitols and xylitols compounds also may provide enhanced flow properties for such mixture, as compared to mixtures using hydrophilic silica. Loading ranges of silica may be important in improving the flow of diacetals of sorbitols and xylitols compounds.
