For the system of Styrene/n-butyl methacrylate/AIBN
copolymeizations were carried out at two sensitive feed monomer composition points by duplicate experiments at 40.60.80.100.120.140℃ respectively
The compositions of copolymer wereanalysized by NMR.The relative reactivity ratios of styrene and BMA were calculated by the error-in-variables method(EVM) of Mayo-Lowis equation
and 95% joint confidence intervals of the reactivity ratios were also given.The results were in according with the the FTIR results.The suggested reactivity ratios of St-BMA system at different temperature were obtained from the linear of measures reactivity ratios and temperatures by regression treatment.
