• Made up of many monomers, individual molecules
• Held together by intramolecular forces
• Dehydration synthesis is adding monomer and releasing water
  • C bonded with H and C bonded with OH remove $H_{2}O$ and bond
• Hydrolosis reaction is adding water and releasing monomer
  • $H_{2}O$ can be added to C bonded to C
• Polymers create four basic types of macromolecules
