Polyacrylamide does not have the toxic effects of acrylamide monomer and is hydrophilic. It can form aqueous solutions of very high concentration and because of their gel-like properties, has been used in the conservation of works of art.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31370838"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14101345"> <skos:prefLabel xml:lang="es">polyacrylamide (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9859399"> <skos:prefLabel xml:lang="ca">polyacrylamide (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:50:11</dct:created>  </skos:Concept></rdf:RDF>
