Abstract:
A product including a furandicarboxylate compound and diol is obtained from a furandicarboxylate containing polyester in a process, which includes reacting a polymer composition including furandicarboxylate containing polyester with water or an alcohol, such as an alkyl alcohol with from 1 to 12 carbon atoms, in the presence of a base, that is preferably selected from the group consisting of metal hydrides, metal alkoxides, metal carbonates, metal carboxylates, N-heterocyclic carbenes, amidines, guanidines, phosphazenes and mixtures thereof.
