polymerisation

Monomers becoming chains

Polymerisation is the chemical process by which small molecules (monomers) link together to form long chains or networks (polymers).

The process creates materials like plastics, rubber, and DNA.

Also spelled polymerization.

The polymerisation of ethylene produces polyethylene.
