Introduction to Polymers

Polymers are large molecules composed of many identical subunits called monomers. They play a crucial role in both natural biological systems, like DNA and proteins, and in human-made materials such as plastics. Understanding polymers is essential in Chemistry.

Overview

Polymers are essential materials that consist of long chains of repeating units called monomers. They can be found in both natural forms, such as proteins and cellulose, and synthetic forms, like plastics and rubbers. Understanding the structure and properties of polymers is crucial for their applic...

Key Terms

Monomer
A small molecule that can join together with other similar molecules to form a polymer.

Example: Glucose is a monomer that forms starch.

Polymerization
The process of combining monomers to form a polymer.

Example: Polyethylene is formed through the polymerization of ethylene monomers.

Covalent Bond
A type of chemical bond where atoms share pairs of electrons.

Example: The bonds between carbon atoms in a polymer chain are covalent.

Thermoplastics
Polymers that become soft when heated and hard when cooled.

Example: Polyvinyl chloride (PVC) is a common thermoplastic.

Thermosetting Polymers
Polymers that harden permanently after being heated and cannot be remolded.

Example: Epoxy resins are thermosetting polymers.

Biodegradable Polymers
Polymers that can decompose naturally in the environment.

Example: PLA (polylactic acid) is a biodegradable polymer used in packaging.
