Describe the types of polymerization - 1.addition and 2.condensation
Describe the types of polymerization (addition and condensation):
Addition
- Addition polymerization involves the addition of monomers without the elimination of any small molecules.
- Addition polymerization can be initiated by heat, light, or chemical catalysts.
- Addition polymerization can produce polymers with high molecular weight and high purity.
- Examples of addition polymers include polyethylene, polypropylene, and polyvinyl chloride.
condensation
- Condensation polymerization involves the elimination of small molecules, such as water, during polymerization. Condensation
- polymerization can produce polymers with low molecular weight and high polydispersity.
- Examples of condensation polymers include nylon, polyester, and polyurethane.
- Condensation polymerization can be carried out using di- or polyfunctional monomers.
- Condensation polymerization can be carried out in solution or in the solid state.
- The properties of condensation polymers can be affected by the reaction conditions, such as temperature and pressure.
- The stereochemistry of the monomers can affect the properties of the resulting polymer.
- The structure of the monomers can affect the properties of the resulting polymer.
- The purity of the monomers can affect the properties of the resulting polymer.
- Polymerization can be a complex process that requires careful control of the reaction conditions.
- Polymerization can be used to create a wide range of materials with unique properties.
