ABSTRACT:
A recyclable polymer is formed of a plurality of oligomer units obtained by polymerizing a fixed number of monomers, and linkage units for linking the oligomer units through a chemical bond which is different from a bond between monomers constituting the oligomer units, thereby allowing repetitive scission and re-bonding of the linkage units by a predetermined treatment not cleaving the bond between monomers. The recyclable polymer is decomposable into oligomers and the oligomers can be linked again into the original polymer without degrading the quality of the polymer. A process for producing the recyclable polymer, a method for recovering the recyclable polymer, and a method for regenerating the recyclable polymer are also provided.
