  • Alkylphenol-free Polymeric Polyphosphite Stabilizer for Polyolefin Compositions for Film, Fiber and Molded Articles
    Publication number: 20160237264
    Abstract: The invention pertains generally to an improved polymer composition which contains at least one liquid polymeric polyphosphite additive containing no alkylphenols. Alkylphenol-free polymeric polyphosphites offer distinct advantages over conventional phosphite technology in polyolefin films. Polymeric polyphosphites offer improved performance in regards to the prevention of color formation during high temperature processing, NOx aging, and gamma irradiation.
