condensation

• • condensation polymerisation involves monomers with different functional groups
• • a small molecule, usually water, is made as a byproduct
• differences between addition and condensation:

  • addition needs one monomer type with a double carbon bond
  • condensation needs one monomer type with two functional groups
  • addition produces only the polymer
  • condensation produces the polymer and small molecule
  • the functional group of addition is a carbon double bond
  • the functional group of condensation is two reactive groups on each monomer
