Characterization and long-term stability of historical PMMA: Impact of additives and acrylic sheet industrial production processesAccelerated agingAdditivesCadmium redConservationPhotodegradationPMMAPoly(methyl methacrylate)Production processesChemistry(all)Polymers and PlasticsSFRH/BD/52318/2013 IF/00653/2015 UIDB/50006/2020 UIDB/04349/2020This work aims at understanding the influence of the production processes and materials in the properties and long term behavior of acrylic sheet, i.e., poly(methyl methacrylate) (PMMA), a material generally considered very stable in museum collections. A comparative study was conducted in samples from cast acrylic sheets produced in the early 2000s, from which manufacturing details were known, and samples provided by the artist Lourdes Castro from acrylic sheets she had bought in the 1960s. Transparent and red opaque cast acrylic samples, containing cadmium red pigment, were used. All samples were artificially aged in a solarbox with irradiation Λ > 300 nm for a total period of 8000 h, and alterations were followed by a multi-analytical approach which included Raman, infrared (FTIR-ATR) and UV-Vis spectroscopies; gravimetry; size exclusion chromatography (SEC); thermogravimetry (TGA); micro-indentation; colorimetry; and optical microscopy. Not all cast PMMA sheets presented similar stabilities. We have concluded that the production processes (which may include the polymerization conditions, the organic additives and the origin of the monomer) play a more important role in the properties and long-term behavior of these acrylic sheets than the presence of cadmium red and/or the age of the material.DCR - Departamento de Conservação e RestauroLAQV@REQUIMTEDQ - Departamento de QuímicaRUNBabo, SaraFerreira, Joana LiaRamos, Ana MariaMicheluz, AnnaPamplona, MarisaCasimiro, Maria HelenaFerreira, Luís MotaMelo, Maria João2021-03-19T23:27:30Z2020-102020-10-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/114136eng1618-7229PURE: 26225879https://doi.org/10.3390/POLYM12102198info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:51:16Zoai:run.unl.pt:10362/114136Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:51:16Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
