Root Explanation

Comonomer is formed from "co-" (meaning together) and "monomer" (from Greek "monos", meaning single, and "meros", meaning part). The word refers to a molecule that is a part of a polymer, specifically when two different types of monomers are combined together.

Memory Tip

Think of 'together' ('co-') and 'single part' ('monomer') to remember that a comonomer is a single part that combines with another to form a larger structure.
