A method of manufacturing an end-use article from a polymeric composition comprising forming an intermediate article of the polymer composition into the end-use article having a gloss retention of greater than about 40%. A method of manufacturing an end-use article from a polymeric material comprising producing an intermediate polymeric article, determining the gloss of the intermediate article, converting the intermediate article to an end-use polymeric article, determining the gloss of the end-use polymeric article and calculating the gloss retention of the end-use article. A method of increasing the gloss retention of a polymeric article, comprising: fabricating an intermediate article from a polymeric composition comprising a metallocene-catalyzed polypropylene and a nucleator, clarifier, or both; and further processing the intermediate article to an end-use article. |
