“…The optimum region for performing quantitative infrared analysis was between 0.3 and 0.6 absorbance unit. Typical polymer concentrations were [3][4][5][6][7][8] wt % within the optimum region. Before scanning the spectrum, the filled infrared cell was placed in the instrument for 15 minutes to allow the sample to reach temperature equilibrium.…”

“…Pyrolysis gas chromatography has been used extensively to qualitatively and quantitatively examine actylic polymers (Radell and Strutz 1959;Lehmann and Brauer 1961; Lehrle and Robb 1967;Esposito and Swann 1965;Ettre and Varadi 1962). Frankoski and Siggta (1972) have also examined alkali fusion reaction gas chromatography in the study of polyacrylates and polymethacrylates.…”

The removability of naturally aged synthetic picture varnishes~as been examined on more than 50 paintings. Most of these paintings had been coated with either poly(isoamylmethacrylate) or poly(n-butylmethacrylate). Since these aged methacrylate coatings were applied between 10 and 40 years ago, questions had been posed about possible cross-linking of the polymer chains, which would make them more difficultto removewith solvents or even render them completely insoluble. These questions were investigated by applying solvents of increasing polarity to the varnish by swab, and analyzing the material removed by infrared spectroscopy. All coatings were found to be removable with solvents, although often fairly polar solvent mixtures were necessary.Only 5 of 25 paintings suspected of being coated with poly(isoamylmethacrylate) were found to be coated with this varnish. The varnish, a type known as 27H, was removed with relatively mild solvents, often by swelling. 'I111IV-onepaintings coated with poly(n-butyl methacrylate) were examined. Although solvents more polar than acetone were not required for removal of the coatings, concerns were raised about the sensitivity of the paint films of early American paintings to that solvent. In addition, although these coatings are removable today, the future aging behavior of these varnishes under the conditions of exposure at the National Gallery of Art, where ultraviolet filters are in place, has not been determined. Continued systematic monitoring of the aging behavior of these varnishes on selected paintings willbe carried out.
