IPA: /ˈpɒlɪmərɪzəm/
KK: /pɑˈlɪmərɪzəm/
The process of creating large molecules made up of repeating units, known as polymers.
Polymerism is essential in the production of many synthetic materials.
Polymerism → It is formed from "poly-" (from Greek "polus", meaning many) and "meris" (from Greek "meros", meaning part). The word describes a condition or phenomenon involving many parts or units coming together to form a whole.
Think of 'many' ('poly-') parts ('meris') coming together to create something larger — that's what polymerism means.
