Polymer: meaning, definitions and examples

Commonly used in scientific or industrial fields to describe a substance composed of large molecules made up of repeating structural units. It can refer to both natural and synthetic materials.

• Polyethylene is a common polymer used in packaging.
• The properties of the polymer can be adjusted by varying its composition.

Often used in chemistry to describe a substance made from two or more different elements that are chemically bonded together in a fixed ratio.

• Water is a compound consisting of hydrogen and oxygen.
• Sodium chloride is a common compound used as table salt.

Used mainly in scientific contexts, especially in biochemistry and molecular biology, to describe very large molecules, typically composed of thousands of atoms. Examples include proteins, nucleic acids, and polymers.

• Proteins are essential macromolecules in biological systems.
• DNA is a macromolecule that carries genetic information.

Used primarily in industry and manufacturing, referring to a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Often involved in making plastics or adhesives.

• Epoxy resin is commonly used in coatings and adhesives.
• Amber is a natural resin known for its ability to preserve ancient organisms.

A general term used in both scientific and industrial contexts to describe large molecules made up of many repeating subunits. Appropriate for discussing chemical substances in various applications.

• The packaging material is made of a durable polymer.
• Scientists are researching new types of polymers for medical applications.

Used in scientific discussions to describe any large molecule, not just polymers. Common in fields like chemistry, biology, and materials science.

• Proteins are an example of a macromolecule important for cell function.
• Studying macromolecules helps scientists understand biological processes.

Suitable for contexts involving natural polymers derived from living organisms. Commonly used in biological, environmental, and medical fields.

• DNA is an important biopolymer found in all living cells.
• Research on biopolymers can lead to sustainable materials.

Appropriate when discussing a specific type of polymer with additional elements or structures. Often used in technical and industrial contexts.

• The new polymer compound has improved heat resistance.
• Engineers designed a polymer compound that is both lightweight and strong.
