1. Monomer

   • a building block of polymeric materials
   • usually a small molecule with polymerisable group(s)

2. Polymer

   • Polymers are very large molecules.
   • Also called macromolecules.
   • Made by reacting a large number (n) of monomer molecules which will be linked covalently to each other.

3. Polymerisation

   • the process by which monomers are converted into a polymer

4. Degree of Polymerisation

   • DP, Xn, n
   • n= 100.....100,000

5. Oligomer

   • 2<n<ca.20

6. Repeat(ing) unit

   • -CH2CH2-
