Towards the Understanding of the Aging Behavior of p-PVC in Close Contact with Minced Meat in the Artwork PO^EMETRIE by Dieter Roth.

ABSTRACT: This paper presents scientific investigations into the materiality and aging behavior of a copy of Dieter Roth's multiple PO^EMETRIE (1968), mainly made of p-PVC components and minced meat, with the aim of informing conservation-restoration strategies. The main issues were represented by plasticizer migration, fat diffusion, and leakage, which led to the formation of a sticky surface layer. Replicas of p-PVC without minced meat were prepared and artificially thermally aged, while several techniques were used to investigate both the artwork and the replicas in terms of materials and degradation state. These include UV/Vis imaging, pH measurements, FTIR-ATR, and Py-GC/MS. In addition to showing that p-PVC-based materials composed of slightly different plasticizers were affec
