The process of converting a polymer into a monomer or a mixture of monomers.
Note:
Unzipping is depolymerization occurring by a sequence of reactions, progressing along a macromolecule and yielding products, usually monomer molecules at each reaction step, from which macromolecules similar to the original can be regenerated.
