Hydrolysing Condensation Polymers

Hydrolysing: Condensation polymers can be hydrolysed using hot aqueous alkali e.g. sodium
hydroxide OR hot dilute aqueous acid e.g. HCl.
 Wherever there is an amide or ester bond, can break it apart and forms products either side of
it. Add water on.
 5) Hydrolysing Polyesters:

6) Hydrolysing Polyamides:
 With acid hydrolysis, if N in original compound, it will actually be NH2+ not NH3+, gains 2H. Will
get N rather than NH when in a cyclic compound usually or tertiary structure because N can have
maximum 3 bonds.
 Also with acid hydrolysis, if NH in the compound but not part of an amide bond, it gains one H
and charge to form NH2+ after acid hydrolysis.
 Acid protonates any amine group- adds a H+ on.
