polymerizations
Making plastic molecules
Polymerizations are chemical reactions in which small molecules (monomers) link together to form large chain-like or networked molecules (polymers).
The process creates materials like plastics, rubber, and synthetic fibers: Industrial polymerizations produce millions of tons of polyethylene annually.
The plural typically refers to multiple instances or types of such reactions.
