Abstract
The artist Jordi Teixidor is one of the leading exponents of twentieth century Spanish abstract art. In
recent years, he has used a synthetic polymer as a support for his art work, namely polypropylene. The
behaviour of this material in combination with layers of oil paint has not been studied until now. One
of the objectives of this study was to chemically characterise the material present in Jordi Teixidors
work, using FT-IR spectroscopy, in order to be able to examine the behaviour of this set of materials
after undergoing cycles of accelerated aging. After subjecting the samples to temperature and relative
humidity cycles and ultraviolet radiation, their physico-mechanical behaviour was determined via tensile
and bend tests, with the results being processed further by means of spectroscopic techniques and colour
measurements. It was found that the possible migration of the additives present in the PP support and the
gradual degradation of the materials could affect the adherence between the paint layers in the future.
