3. Polymer
 Many molecules all strung together to form really long chains (and
sometimes more complicated structures, too) makes Polymers

5. What Is Polymerization?
In polymer chemistry, polymerization is a process of reacting monomer
molecules together in a chemical reaction to form polymer chains or three-
dimensional networks
Polymerization

6. Types of Polymerization:

7. Addition/Chain Growth PolymerizationCondensation/Step
Growth Polymerization

8. Two main characteristics of Condensation Polymerization
 Instead of double bonds, these monomers have functional groups (like
alcohol, amine, or carboxylic acid groups).
 Each monomer has at least two reactive sites, which usually means two
functional groups.

9. Functional Groups
Functional groups are specific groups of atoms or bonds within molecules that are responsible for
the characteristic chemical reactions of those molecules. The same functional group will undergo
the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of.

10. Linkage/Formation
 The Amide Linkage:
 When a carboxylic acid and an amine react, a water molecule is removed, and an amide molecule is
formed.
 Because of this amide formation, this bond is known as an amide linkage.
 The Ester Linkage:
 When a carboxylic acid and an alcohol react, a water molecule is removed, and an ester molecule is
formed.
 Because of this ester formation, this bond is known as an ester linkage.

11. Examples
 Example 1:
A carboxylic acid monomer and an amine monomer can join in an amide linkage.
 Example 2:
A carboxylic acid monomer and an alcohol monomer can join in an ester
linkage.

12. Continuity

13. Conclusion
 Polymerization is important because it is how plastics are made and many
of our products contain plastics. Polymerization is also how your body
makes proteins In general, lots of the things around us are polymers,
include:
 Anything plastic
 Proteins, such as hair, nails, tortoise shell
 Cellulose in paper and trees
 DNA
 Rubber and how plants make starch.
