    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.
