Are they not just the same thing?

polypeptides is just one of the example of polyamides
but there are many polyamides, that means in a polymer there are many amide bonds. e.g. Nylon-6.6
steve_geo1 mentioned about "alpha" amino acids to form polypeptide. It is not necessarily true anymore. Biochemists have synthesized "beta" and "gamma" amino acids and use these monomers to mimic natural peptides for antibiotics since they don't undergo degradation like "alpha" peptides.

All polypeptides are polyamides, but not all polyamides are polypeptides. An example of a polyamide that is not a polypeptide is nylon-6:
-[-NH-CH2CH2CH2CH2-CO-]n-
A polypeptide must be formed from *alpha*-amino acids.
