Materials made from polyolefins used in tasks of preventive conservation: A comparative study of their long-term behavior

ABSTRACT: In this paper, the results corresponding to the study of different materials used in the field of Preventive Conservation have been presented. All of them are polyolefins, but show differences related to the type of polyolefin and the nature of additives. Their long-term behaviour has been evaluated by performing accelerated artificial aging (arc-xenon aging) and changes in their original composition and properties have been determined. The analytical techniques used have been: FTIR-ATR, Py-GC-MS, DSC, TGA, and GPC.
