Abstract
In this study, we propose an infrared spectrometry technique to determ ine the copolymer composition. Polysulfones are copolymerized by acryl amide and sulfur dioxide at various conditions. The copolymer's compos ition is measured as a function of the ratio of the absorbance of the CH2 group (1423 cm(-1)) to the absorbance of the SO2 group (1305 cm(-1 )). Using this linear relation, the copolymer composition can be easil y determined without repeating the experiment of an element analysis i n the range of 2.83-11.96. Experimental results confirm that this tech nique applied to poly(styrene sulfone) is valid for the copolymer in t he range of 1.27-5.25. The data and the linear relationship correlate well with each other. (C) 1997 Elsevier Science Ltd.
