A polymer composition comprises a polyolefin and a nucleating or clarifying agent dispersed or dissolved in the polyolefin. Methods for producing the polymer composition and method for producing articles from the polymer composition are also described. Molded polymer articles and polymer film may be manufactured using the compositions of the invention.

Polymer compositions comprising nucleating or clarifying agents and articles made using such compositions

Novel thermoplastic articles that contain novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat any discoloring within clear, colorless applications), are substantially non-migratory from target resins, and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided. In effect, the inventive thermoplastic articles, provide excellent protection for certain vitamins, flavorings, and colorants, for example, from ultraviolet degradation, particularly above the 370 nm wavelength that is typically the high end of protection for clear thermoplastics having low migratory, colorless UV absorbers therein.
