Addition Polymerization

Condensation Polymerization

1. Monomers must have either a double bond or triple bond

1. Monomers must have two similar or different functional groups

2. No by-products are obtained

2. By-products such as ammonia, water, and HCl are obtained.

3. Addition of monomeric units produces polymers.

3. Condensation of monomeric units produces polymers.

4. The resultant polymers have a molecular weight that is a multiple of the molecular weight of the number of monomers.

4. The resultant molecular weight of the polymer is not a multiple of the monomer’s molecular weight.

5. In addition to polymerization, Lewis acids or bases, radical initiators are catalysts.

5. Condensation polymerization catalysts are catalysts for condensation polymerization.

6. Common examples of addition polymerization are PVC, polyethylene, Teflon etc.

6. Common examples of condensation polymerization are nylon, bakelite, silicon, etc.
