Summary We describe here the synthesis of a new tin chelate Sn(C6H5O3)2.2H2O. The catalytic performance of this chelate is shown for polyesterification reactions involving terephthalic acid and poliols, such as neopentylglygol and trimetilolpropane. The complex is highly active for low molecular weight (Mn= 1700 and Mw= 4500) polymer formation. IR spectra also show free OH in the polymer chain.
