Title: deterioration Long Title: IUPAC Gold Book - deterioration DOI: 10.1351/goldbook.13902 Status: current Definition Deleterious alteration of a material in quality, serviceability, or vigor. Notes 1) Deterioration can result from physical and/or chemical phenomena. 2) Deterioration is connected to a loss of performances and thus to the function, whereas degradation is connected with a loss of properties. 3) Polymer deterioration is more general than polymer degradation, which reflects loss of properties resulting from chemical cleavage of macromolecules only.
