Hydroxyphenylalkyleneyl isocyanurate/thiophosphite combinations as stabilizers for organic materials

摘要

Organic materials subject to thermal and/or oxidative degradation are efficiently stabilized using a combination of a hydroxyphenylalkyleneyl isocyanurate compound and a thiophosphite compound. The stabilized compositions exhibit exceptional stability, better than that achieved using either compound alone or using any known combination of phenolic and phosphorous-containing stabilizer compounds.
