Addition Polymers
Addition polymers were introduced at AS
They are created from alkenes (called monomers) in a free radical addition reaction
They don't biodegrade

Condensation Polymers
Condensation polymers appear in amino acids
Each monomer has at least two functional groups
They are formed from condensation reactions - loss of a water molecule
They are biodegradable as they return back to their monomers through hydrolysis

Polyamides
Polyamides have the link -CONH- from the carboxyl and amino groups
