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).

Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition. Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
