Their\r\nconservation is tailored to the plastic type or polymer, but the role of additives within\r\na plastic formulation can be overlooked. Plasticiser additives are used to\r\nmanufacture CA and PVC and are designed to remain within the plastic to impart\r\nflexibility. Instead, they can migrate out of the plastic due to the surrounding\r\nenvironment or the plasticiser’s chemical characteristics. As such the additive can\r\ninfluence the migration rate and consequently aging behaviour of a plasticised\r\nobject, but few studies have linked an objects degradation behaviour with the\r\nadditives present.\r\nNon-destructive methods were developed for PVC identification using new ATR\r\nlibraries and ER-FTIR spectroscopy. ER-FTIR spectra were also used to identify\r\naromatic plasticisers without requiring destructive GC-MS or NMR methods.\r\nAdditionally, a minimally invasive sampling method using surface swabs were shown\r\nto allow sampling of degradation products, before a simple, cost-effective thin layer\r\nchromatography method can be used to widen the range of observable analytes\r\nversus the ER-FTIR spectroscopy method.\r\nFor CA, a preliminary attempt at magnetic resonance imaging suggested water and\r\nplasticiser content could be studied across three-dimensional CA samples.\r\nAdditionally, a new data processing method for 1H NMR data allows for the\r\nmeasurement of additive and acetic acid concentrations, as well as the degree of\r\nsubstitution within a single sample. It is hoped the method can be developed further and used to identify links between chemical composition and degradation behaviour\r\nfor objects.\r\nOverall, the proposed techniques aim to enable conservation practitioners to assess\r\nthe condition and composition of plastic objects in museum collections. By employing\r\nthese methods, conservators can gain insights into the effect of a plastic object’s\r\nadditive formulation on its aging behaviour."^^<http://www.w3.org/2001/XMLSchema#string> .
