ABSTRACT
A rapid method for quantitative determination of the composition of statistical terpolymers of styrene, butadiene, and isoprene by IR attenuated total reflection (ATR) spectroscopy is described. A quantitative model is designed with the aid of H NMR spectroscopy. This method does not require that the test samples be dissolved or their thickness be monitored precisely, and records the IR spectrum of the rubber rapidly (<5 min). It is easily reproduced and has good convergence. The relative error is less than 5 %.
