These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation …
WebΔS p < 0, it depolymerizes only at temperatures above ceiling temperature T c ≅ ΔH p/ΔS p (ΔH p < 0 is poly- merization enthalpy). Rarely, such as in polymerization of sulfur S 8, ΔS p > 0 and also ΔH p > 0, and thus depolymerization prevails below so-called floor temperature T f ≅ ΔH p/ΔS p (Penczek et al., 2008).
