Abstract
The kinetics of the transesterification reaction between PET and PES was studied with data obtained by NMR spectra. Assuming a second-order reaction, the rate constant k takes an almost constant value over-all samples having different feed ratios, except during the initial stages of the reaction. This demonstrates that the transesterification reaction is second-order. (The concentration of catalyst is constant.)
