    • A monomolecular oxo-piperazinyl triazine (''PIP-T'') having a single triazine ring and three piperazinone substituents, each with an unsubstituted N atom, used in an amount no more than 0.2 phr, and without any secondary stabilizer (hence referred to as a ''virgin PIP-T''), and in particular, without any hindered phenol antioxidant, or phosphorous acid ester, simultaneously provides thermooxidative stability, and stability against degradation by UV light. Further, the virgin PIP-T provides (i) adequate melt processability to permit uninterrupted operation of a die or mold while maintaining the surfaces of the cavities essentially contaminant-free; and, (ii) excellent AO stabilization, equivalent to that obtained with a premier hindered phenol AO, and superior to that obtained with the premier oligomeric piperidinyl-triazine compound, when each stabilizer is used in the same amount by weight in a thermoplastic synthetic resinous substrate.
