Probing the factors which control degradation in museum collections of cellulose acetate artefacts
Cellulose acetate artefacts in museum collections cover a period from the early 1900's to the present day. Conservators have observed that certain of these objects are showing signs of warping, crazing, cracking, discolouration and shrinkage accompanied by a strong smell of acetic acid. Previous studies on cellulose nitrate artefacts show...Ballany, Jane M ; Littlejohn, D ; Pethrick, R P ; Quye, Anita

Analytical studies of the degradation of cellulose nitrate plastics in museums
This paper discusses a project which is examining the degradation of cellulose nitrate artefacts. Several analytical techniques including Fourier transform infrared (FTIR) spectroscopy and ion chromatography have been used to investigate the degradation processes occurring and the various factors influencing the rate of degradation. Accelerated ageing of cellulose nitrate has...Stewart, R ; Littlejohn, D ; Pethrick, R P ; Quye, Anita ; Tennent, N H

The use of accelerated ageing tests for studying the degradation of cellulose nitrate
Previous studies have shown that high levels of sulphate in cellulose nitrate artefacts may be a cause of increased degradation. Accelerated ageing tests have been used to study and monitor the deterioration of prepared cellulose nitrate samples and artefacts over time. An evaluation has been made of the effects of... -

Investigation of inherent degradation in cellulose nitrate museum artefacts
Cellulose nitrate was one of the first semi-synthetic plastics to be commercially exploited and as such many museums contain a large number of artefacts illustrating the versatility of this plastic for the creation of a wide variety of functional and aesthetic artefacts. Conservators find themselves faced with the challenge of...Quye, Anita ; Littlejohn, D ; Petherick, R ; Stewart, R

Investigation of the degradation of cellulose acetate museum artefacts
Cellulose acetate artefacts from various museums have been analysed by micro-FTIR spectrometry and ion chromatography in an attempt to identify whether there are any common factors associated with their degradation. There was good correlation between the IR spectra, the concentration of ions extracted from an artefact and the visual degree...Littlejohn, D ; Petherick, R ; Quye, Anita ; Ballany, Jane M
