polymerization
/,pɔliməri'zeiʃn/
Definition
- Noun:
- A chemical process that combines several monomers to form a polymer or polymeric compound: "Polymerization" refers to a chemical reaction in which small, simple molecules (monomers) link together to form a large, chain-like or network molecule (a polymer).
Usage
- As a subject of a sentence: "Polymerization" is often discussed as a process or phenomenon.
- Polymerization is essential for creating many plastics.
- As an object of a verb or preposition: It is used to describe what is happening or being studied.
- The chemist initiated the polymerization by adding a catalyst.
- This material is formed through a process of polymerization.
Examples
Advanced Usage
- "Living polymerization": A type of polymerization where the polymer chain ends remain active and capable of further growth, allowing for precise control over the polymer's structure.
- Living polymerization techniques enable the synthesis of block copolymers.
- "Step-growth polymerization": A polymerization mechanism where bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers, and eventually long-chain polymers.
- Nylon is typically produced by step-growth polymerization.
- "Chain-growth polymerization": A mechanism involving the sequential addition of monomer units to a reactive center, such as a free radical or ion.
- The polymerization of styrene often proceeds via chain-growth mechanisms.
Variants and Related Words
- Polymerize (verb): To undergo or cause to undergo polymerization.
