A chapa acrílica, também conhecida pelos nomes comerciais Plexiglas ou Perspex, consiste em poli(metacrilato de metilo) (PMMA). Atractiva para os artistas desde o seu desenvolvimento na década de 1930, popularizou-se durante a década de 1960. Estudos sobre a sua utilização e estado de conservação são escassos em Portugal. Realizou-se um levantamento nas principais coleções de arte portuguesas com o objetivo de obter uma visão geral da presença e estado
da chapa acrílica nesse contexto. É descrita a metodologia utilizada e os resultados obtidos relativamente a 137 obras de 69 artistas, inventariadas como contendo acrílico. Os resultados
mostram que este material tem sido utilizado pelos artistas portugueses pelo menos desde os anos 60 até aos dias de hoje, em diversas formas artísticas, que vão desde a pintura e a escultura à fotografia, instalação, objetos/relevos e livros de artistas. A maioria das obras encontra-se em bom ou razoável estado. Os principais danos observados foram depósitos de poeira e sujidade, abrasões e riscos.
