4. 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

5. What are polymers?

6. Addition
Polymerization
Condensation
Polymerization
monomers have two
functional groups or
combining two molecules
by removing a small
molecule
monomers have double
bonding ( C = C)
