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.
