An analytical study of polypropylene as a support for paint layers. From concept to material in contemporary art

ATR-FTIR characterization of old pressure sensitive adhesive tapes in historic papers

“…The spectrum of the backing of unaged commercial tape PP-SR shows (Fig. 5) the typical absorption bands of polypropylene [18,19]. The major ATR-FTIR features are as follows: a characteristic quadruplet at 2951, 2871 cm −1 (attributed to C H stretching of CH 3 groups), 2917, 2837 cm −1 (due to C H stretching of CH 2 groups) and two absorption peaks at 1455 cm −1 (assigned to C H bending of CH 2 ) and at 1375 (attributed to C H bending of CH 3 ).…”

A theoretical comparison between the restoration of two contemporary works of art made of plastic

“…Their small molecules occupy positions between the large polymer chains, increasing the distance between chains and reducing secondary intermolecular links. The migration loss of these compounds alters the mechanical properties of the polymers and has serious consequences [14], as in this case. For this reason, the shoes were adhered at many points on themselves, having lost their characteristic volume and shape.…”

An analytical approach for the non-invasive selection of consolidants in rubber artworks

“…Infrared spectroscopy is widely used for polymer identification and ATR-FTIR shows excellent results in polymer characterization [1]. Accelerated aging experiments have already been employed in several researches in order to study the materials surface deterioration [16][17][18][19]. By increasing the understanding of polymer properties valuable improvements of the treatments and of the materials employed can be obtained.…”
