ABSTRACT
Synthetic polymers were used for the fabrication of artworks since their introduction as industrial materials and, as a matter of fact, sculptures (including assemblages, collages and installations) partially or completely made of plastics are ubiquitous in art collections and contemporary art museums. On the other hand, it is well known that polymers may be much more prone to oxidation and more in general to physical or chemical ageing, than other materials traditionally used by artists, even under protected indoor conditions such as those found in museums during display or storage (Shashoua 2008, Lazzari et al., 2011, Toja et al., 2012).
