Absorbance spectra of seven polymers were established in the wavelength range of 191.5–750 nm and the highest absorbance was recorded at 191.5 nm for all polymers. UV absorbance of the polymers gradually decreased between 191.5–240 nm and a strong linear relationship (R2 > 0.97) between concentration and absorbance held at 191.5, 200 and 210 nm.
