Kinetics of copolyesterification between poly(butylene terephthalate) PBT and 4-acetoxy benzoic acid (ABA) in the melt have been analyzed using a simple approach. A simple second order reaction sequence summarizes catalysed and uncatalysed reactions between ABA and PBT. The kinetic parameters for the copolymerization reaction were determined using a simultaneous non-linear programming method. This technique was used to compute the moles of ABA reacted. This data was compared to that of the experimentally determined data. Close comparison (R.M.S. error ±0.003) was obtained between the experimental and theoretical data. The kinetic data support block copolyester formation. The thermal data also gave support to this behavior.
