摘要： A polymeric article, such as an extruded or molded article or a biaxially oriented tape of film, and a method of stabilizing such a polymeric article to protect the article from degradation due to exposure to UV light. The article is formed by blending a polymeric material with from about 50 to about 5,000 ppm of at least one ortho hydroxy tris-aryl triazine light absorber and from about 500 ppm to about 1.25 percent of at least one oligomeric, polymeric, or high molecular weight HALS having a molecular weight of at least about 500, wherein the weight ratio of HALS to triazine light absorber is from about 3:1 to about 20:1, to form a stabilized polymeric composition, and forming an extruded or molded article or a biaxially oriented tape or film from the stabilized polymeric composition.

摘要： The cycle time of polymer compositions subjected to a rotomolding process is improved (i.e., reduced), while the processing window is simultaneously enlarged through the use of a polymer-stabilizing amount of a processing stabilizer system having at least one chroman-based compound according to Formula V:
