Abstract: 
Many modern analytical techniques are available for characterising ageing-induced changes in sealants. These techniques are derived from the areas of thermal analysis, spectroscopy, microscopy and methods for assessing the crosslinking density and molecular weight distribution. While these modern analytical techniques show much promise in providing fast and reliable information which is complimentary to conventional mechanical tests, the study of ageing-induced effects in sealants with these methods is still in its infancy. The chapter summarises the current state-of-the-art in the use of modern analytical techniques for the characterisation of ageing induced effects in sealants, identifies gaps in our knowledge and makes recommendations for further research. A concerted effort between academic and industrial research is needed to demonstrate and improve the utility of these methods.
