A research programme on the identification and behaviour of PVC materials was undertaken in liaison with the Museums of France Research and Restoration Centre (C2RMF), primarily from analyses carried out on pure PVC resins, current consumer products and works of art, particularly inflatable structures.

This project focuses on celluloid, a material widely used during the 20th century but which has become almost obsolete due to the risks associated with its usage, as well as its stability. The project has yielded proposals for conservation and treatment measures drawing on studies carried out on heritage works.


Duration: 2010–2011

CICRP: Alain Colombini

Partnership(s): Research Centre for the Conservation of Collections (CRCC), Laboratory of Molecular and Macromolecular Photochemistry (LPMM); Museums of France Research and Restoration Centre (C2RMF); Gwenola Corbin, conservator-restorer, National Centre of Plastic Arts (CNAP) grant

Under the restoration research allowance granted to Gwenola Corbin by the National Centre of Plastic Arts (CNAP), the CICRP has provided scientific assistance to this research project. The topics addressed have focused on identification techniques for rubbers present in museum collections, their degradation processes and their consolidation.

Partnership(s): Clémentine Bollard, art restorer, grant holder of the National Centre of Plastic Arts (CNAP), Museums of France Research and Restoration Centre (C2RMF)

This programme draws on research carried out by Clémentine Bollard, art restorer, CNAP grant holder. The scientific assistance of the CICRP in this project is based on evaluations of the impact of these treatments with Raman imaging analyses. This work is carried out in coordination with the 20th-century department of the C2RMF and concerns the use of gels for the cleaning of plastics, especially PVC, PMMA and ABS.


Programme start: 2007

Partnership(s): the National Forensic Institute and the Marseille physico-chemical laboratory

The purpose of this research programme on the degradation and consolidation of polyurethane resins/paints and latex-rubber is to optimise consolidation methods of these two materials, allowing the display and easier handling of works, as well as prolonging their ‘life expectancy’.

The results from the study on the mixed artistic technique (acrylic paint applied together with latex on a polyurethane foam support) was presented in 2009 to the French Section of the International Institute for Conservation: ‘Art of today – Heritage of tomorrow: Conservation and restoration of contemporary works’, Paris.

For natural and synthetic rubber, this programme has drawn on work carried out by restorer Gwenola Corbin under a grant from the National Centre of Plastic Arts (CNAP) relating to the degradation of rubbers and for which the CICRP was the designated laboratory. Various treatments were tested combining the use of consolidants and antioxidants rarely used in the field of heritage conservation and restoration.

The research was carried out in 2012 with the identification of consolidating materials compatible with rubber and associated to a treatment providing protection against oxidation reactions and ozonolysis, without modifying the appearance of the works. It will provide a deeper knowledge of natural rubber (identification in collections, degradation processes etc.) and a closer relationship with the industrial sector specialising in this polymer.
