  2. 2. Copolymer Natural polymer Synthetic polymer Thermoset polymer Homopolymer Thermoplastic polymer POLYMER MONOMER POLYMERIZATION (addition & condensation) USES
  3. 3. Basic Competence  To describe structure , naming , classification , properties and uses of the macromoleculars Learning Objectives By the end of this matter, students should be able to : • To identify natural polymers and synthetic polymers (rubber, carbohydrate, protein and plastic) • To write polymerization of the polymers • To desribe uses of polymers
  4. 4. What are polymers?
  5. 5. Addition Polymerization Condensation Polymerization monomers have two functional groups or combining two molecules by removing a small molecule monomers have double bonding ( C = C) n R4R2 R3R1 R1 R2 R3 R4 n Monomers Addition Polymer
  6. 6. Steps in addition polymerization of ethylene
