Abstract
The invention provides a depolymerization method for a polymer containing an ester bond in a main chain, by causing a solid acid catalyst to act on a polymer containing an ester bond in a main chain to depolymerize the polymer, thereby obtaining a re-polymerizable monomer and/or oligomer as a depolymerization product, and a method for producing a polymer containing an ester bond in a main chain, by polymerizing the re-polymerizable monomer and/or oligomer obtained by the depolymerization method.
