WebThe term polymer is a composite of the Greek words poly and meros, meaning “many parts.”. Polymers are large molecules made of small, repeating molecular building blocks called monomers. The process by which monomers link together to form a molecule of a relatively high molecular mass is known as polymerization. The word monomer comes from mono- (one) and -mer (part). Monomers are small moleculeswhich may be joined together in a repeating fashion to form more complex molecules called polymers. Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called … See more Examples of monomers include vinyl chloride (which polymerizes into polyvinyl chloride or PVC), glucose (which polymerizes into starch, cellulose, laminarin, and … See more Examples of polymers include plastics such as polyethylene, silicones such as silly putty, biopolymers such as cellulose and DNA, natural … See more The word polymer comes from poly- (many) and -mer(part).
