Abstract

Abstract: For the system of styrene/n-butyl methacrylate/AIBN, copolymerizations were carried out at 40℃, 60℃, 80℃, 100℃, 120℃, 140℃ respectively.The compositions of copoly-mers were analyzed by FTIR.The relative reactivity ratios of St and BMAare calculated by the error-in variables method, and 95% joint confidence intervals of the reactivity ratios are also given.The relative reactivity ratios of St-BMAsystem at different temperatures were obtained from the linear relation of relative reactivity rarios and temperatures by regression treatment.

Key words: Relative reactivity ratio, FTIR, St-BMA
