Abstract
Degradation-resistant polyolefin articles, such as fibers, films, sheets and the like, are prepared from polymeric compositions containing a stabilizing system comprising a hindered amine and a nickel phosphonate which have been overcoated with a finish comprising an ethoxylated lubricant and a phosphate ester. In a preferred embodiment, polypropylene textile materials having improved thermal stability are provided compositions containing a stabilizing system comprising a hindered amine and a nickel phosphonate which have been overcoated with a finish composition comprising an ethoxylated lubricant and a phosphate ester in an amount sufficient to impart antistatic properties to said composition and increase the thermal stability of said polypropylene textile materials.
