IPA: /ˌpɒlɪməraɪˈzeɪʃən/
KK: /pɑːlɪməraɪˈzeɪʃən/
A chemical process in which small molecules called monomers join together to form a larger molecule known as a polymer.
The polymerisation of the monomers resulted in a strong and flexible material.
Polymerisation → It is formed from "poly-" (from Greek "polus", meaning many) and "meris" (from Greek "meros", meaning part). The word "polymerisation" refers to the process of combining many parts (monomers) to form a larger structure (polymer).
Think of 'many' ('poly-') parts ('meris') coming together to create something larger — that's what polymerisation means.
