Optical absorption of some polymers in the region 240–170 nm

Abstract
Absorption coefficients for some technologically important polymer materials are given in the wavelength range ∼240–170 nm. Absorption coefficients at 193 nm for these polymers show a wide range of values from ∼2×102 cm−1 for polytetrafluoroethylene (Teflon) to ∼4×105 cm−1 for polyimide. The general nature of the optical properties of polymers in the vacuum ultraviolet is also discussed.
