USES
Basic Competence To describe structure , naming , classification , properties and
uses of the macromoleculars
Learning ObjectivesBy 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
What are polymers?
Addition Polymerization
Condensation Polymerization
monomers have two functional groups or combining two molecules by removing a small molecule
monomers have double bonding ( C = C)
