Explain the formation and breakdown of polymers?

Polymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule. ... This is the reverse of a dehydration synthesis reaction, and it releases a monomer that can be used in building a new polymer.
