A type of polymer made up of a small number of repeating units called monomers, typically two to four.
The scientist studied the properties of an oligomer to understand its behavior in chemical reactions.
Oligomer → It is formed from "oligo-" (from Greek "oligos", meaning few or little) and "meros" (from Greek "meros", meaning part). The word "oligomer" refers to a molecule that consists of a few repeating units or parts.
Think of 'few' ('oligo-') parts ('meros') coming together to form a larger structure — that's what an oligomer is.
