What are polymers?

Polymers are macroscopic molecules composed of smaller monomers.

2
New cards

What are the two types of polymers?

  • Natural - silk, cotton, carbohydrates, proteins,…

  • Synthetic - platic, rubber, fibers,…

What are the two main processes to produce a synthetic polymer?

  • Addition

Includes the joining unsaturated monomers together to form an additional polymer link.

  • Condensation

The joining of two different monomers through elimination of H₂O or other small molecules.

Copolymers vs Homopolymers

Copolymers are polymers formed from two different monomers.

Homopolymers are polymers formed from continuous links of the same monomer.

  • Addition reactions can form both depending on the individual reaction.

  • Condensation reactions always form copolymers.

What are the three steps to all polymerization reactions?

  1. Initiation - Just getting started.

  2. Propagation - building up one monomer at a time.

  3. Termination - completing the ends to prevent more monomers from bonding.
