We have developed a general heterogeneous catalytic method for selective transesterification of polyesters with different alcohols. The catalytic activity is correlated to the facile activation of the ester carbonyl bond by Lewis acid sites of the catalyst species in the co-presence of alcohols. Our method has the following advantages: (1) recyclable catalyst, (2) higher TON, and (3) easy catalyst/product separation.
