  • Hydroxyphenylalkyleneyl isocyanurate/pentaerythritol phosphite combinations as ultraviolet light stabilizers for polyolefins
    Patent number: 4025486
    Abstract: Polyolefin polymers subject to degradation on exposure to ultraviolet light are efficiently stabilized using a combination of a hydroxyphenylalkyleneyl isocyanurate compound and a pentaerythritol phosphite compound. The stabilized compositions exhibit exceptional stability to UV light, better than that achieved using known combinations of phenolic and phosphorous-containing stabilizer compounds.
