Study Notes
Origins of Polymers
- The term 'polymer' originates from the Greek words "poly" meaning many and "meros" meaning parts.
Importance of Polymers
- Polymers have enriched human life by providing a wide range of applications in daily life.
Composition of Polymers
- Polymers are constituted by a long chain of repeating molecules or monomers.
- The molecular mass range of polymers is between 10,000 to 100,000 grams per mole.
Chemical Composition of Polymers
- Polymers are chemically made up of carbon and hydrogen atoms, with oxygen, nitrogen, and other elements also present.
Examples of Polymers
- Plastics are an example of man-made materials used in daily life, commonly used in packaging, furniture, and household items.
- Biodegradable polymers, such as cellulose, can be broken down by microorganisms.
Applications of Polymers
- Polypropylene is a polymer commonly used in the manufacture of toys and combs.
History of Polymers
- Hermann Staudinger received the Nobel Prize in Chemistry in 1953 for establishing the macromolecular nature of polymers.
- A hundred years ago, macromolecules were considered as associated molecules, but are known today as macromolecules or polymers.
