IPA: /kəˈmɒnəmər/
KK: /kəˈmɒnəmər/
A substance that is combined with another to form a copolymer, which is a type of polymer made from two or more different monomers.
In the production of plastics, a comonomer is often added to enhance the properties of the final product.
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.
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.
