	abstract = "Analysis of polyethylene additives by means of ultraviolet spectroscopy is limited by excessive beam dispersion due to light scattering from the polymer crystalline regions. Additives at low concentrations (0.1%) require sample thicknesses such that analysis must be performed in the presence of a high level of scattering which may change unpredictably with wave length. At lower levels of concentration and correspondingly greater sample thicknesses, unacceptable signal-to-noise ratios exist. Nevertheless, ultraviolet spectroscopy remains an attractive method for analysis of many additives. Principal advantages over infrared analysis include greater sensitivity arising from higher extinction coefficients and a lack of interfering absorptions from the polyethylene matrix. These advantages can be realized, however, only if background scattering from the polymer can be reduced.",
