摘要： 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.

摘要： Bicyclic nucleator compounds that provide highly versatile nucleation benefits for different polyolefins are provided. Such nucleator compounds provide very high peak crystallization temperatures and significantly reduced crystallization cycle time for certain thermoplastic formulations with or without the presence of other calcium stearate and/or peroxide components within the same type of formulation. Furthermore, such inventive nucleator compounds exhibits very little if any fugitivity from such thermoplastic formulations thereby providing excellent processing characteristics as well as excellent nucleation capabilities for a variety of different thermoplastic resins, independent of the presence of different, potentially necessary, additives (such as calcium stearate). Thermoplastic compositions as well as thermoplastic additive packages comprising such inventive nucleator compounds are also contemplated within this invention.

摘要： Certain thermoplastic additives (combinations of clarifying and nucleating compounds) that induce simultaneously low clarity and high nucleation efficacy are provided. Such additives include combinations of certain bicyclic salts (which by themselves induce very high nucleation efficacy) and thermoplastic clarifying agents, including certain dibenzylidene sorbitol acetals and derivatives (hereinafter collectively referred to as “DBSs”)(which alone provide very low haze measurements and thus highly desirable clarity characteristics). In comparison, other types of standard thermoplastic nucleators, such as sodium benzoate and sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl) phosphate provide relatively high peak crystallization temperatures, but do not combine synergistically with clarifiers, such as DBSs, to provide the same results as for the inventive combination of bicyclic salts and DBSs. Thermoplastic compositions as well as thermoplastic additive packages comprising such inventive nucleator compounds, as well as methods of producing polypropylene compositions and articles made therefrom, are also contemplated within this invention.

摘要： This invention relates to novel ultraviolet absorbing methine-based compounds comprising polyoxyalkylene moieties. Such compounds provide excellent, inexpensive, protection from ultraviolet exposure within various media, including, but not limited to, thermoplastics. The presence of polyoxyalkylene chains on the methine backbone permits such an introduction within thermoplastics while simultaneously providing very low degrees of migration from the target substrate. This invention also concerns methods of making the aforementioned ultraviolet absorbing thermoplastic compositions.
