Study Notes
Polymers
- A large molecule composed of repeating small molecule units is called a polymer.
- The term "polymer" is derived from the Greek words "poly" meaning many and "meros" meaning part.
- The degree of polymerization (DP) represents the number of repeating monomer units in a polymer's chemical structure.
- The small molecule precursor or building block of polymers is called a monomer.
- The chemical structure of polymers typically represents a chain of repeating monomer units.
Types of Polymers
- Polyethylene is a type of polymer with a wide range of applications, including packaging, plastic bags, and insulation.
- Polypropylene is a type of polymer that is denser, stiffer, and harder than polyethylene due to the added methyl groups.
- Thermoplastic polymers can be melted and reshaped by applying heat and pressure due to chains interacting only through intermolecular forces.
- Polyvinyl chloride (PVC) is a type of polymer formed from monomer units vinyl chloride and is used in pipes, floorings, garden hoses, and raincoats.
Polymerization Processes
- Addition polymerization is a type of polymerization process that involves the linking of monomer units with no loss or gain of material.
- Condensation polymerization is a type of polymerization process that involves the linking of bifunctional polymers to give polymer and some small molecules, such as water.
- Polyesters are a type of polymer formed via condensation reaction between diol and diacids, producing water as a by-product.
Properties and Applications
- Thermoplastic polymers are used in making flexible bottles, packaging, toys, films, sheets, and insulation for electric wires.
- Polymers produced via addition polymerization include polyethylene and polypropylene.
- Polymers produced via condensation polymerization include polyesters and polyamides.
- Condensation polymers are a class of polymers that involve the linking of monomer units with no loss or gain of material.
