What is the chemical reaction that creates polymers called?

The process that creates polymers is known as polymerization. This is a chemical reaction in which small molecules, called monomers, combine chemically to form a larger compound, or polymer. During polymerization, the individual monomers undergo a series of reactions, leading to the formation of long chains or networks of repeating units that constitute the polymer.

Polymerization can occur in various ways, including addition polymerization, where monomers add together without the loss of any small molecules, and condensation polymerization, which involves the loss of small molecules (such as water) as byproducts. However, the term that specifically refers to the entire process of forming long-chain molecules from smaller units is polymerization itself. Understanding this concept is crucial in cosmetology, as many beauty products contain polymers that provide specific properties, such as thickness or flexibility, important for their function and application.
