Abstract The catalytic activity of different compounds (dibutyl tin oxide, titanium tetrabutoxide, zirconium tetraethoxide, and para ‐toluenesulfonic acid) for transesterification reactions between polymers was studied. This study was carried out on three different reactions: between two model compounds (methyl benzoate and octyl acetate), between a polymer and a model compound (ethylene‐vinyl acetate copolymer and methyl benzoate), and for crosslinking of ethylene‐vinyl acetate copolymer with dimethyl terephthalate. For these three reactions dibutyl tin oxide presented the higher catalytic activity. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 79: 1556–1562, 2001
