Understand how to deduce the structure of a monomer from the repeat unit of an addition polymer and vice versa

Deducing Structure of a Monomer from a Repeat Unit

To deduce the structure of a monomer from a repeat unit of an addition polymer, you just need to reverse the process of drawing a repeat monomer described in Specification Point 4.45:

  • Identify the repeating unit.
  • Change the single bond in the repeat unit to a double bond in the monomer.
  • Remove the bond from each end of the repeat unit.
