Types of Polymers

• Condensation (Elimination) polymers
• Polyamides
• diacid diamine ? polyamide water

12
Nylon--66

• adipic acid (hexanedioic acid)
• 1,6-hexanediamine

13
Nylon-66
14
Polypeptides

• alanine
• glycine
• isoleucine

15

• Polypeptide forms by eliminating H2O forming
  amide.

16
Hydrolysis of Polypeptide

• The polypeptide can be hydrolyzed (digested) by
  breaking the amide bonds.

17
