    Study Notes

    Types of Polymers

    • Homopolymer: consists of relatively long sequences of identical monomeric units
    • Copolymer: consists of a mixture of more than one type of monomer

    Physical Properties of Polymers

    • Thermoplastic: softens on heating and can be converted to any shape by molding
    • Isotactic polymer: a polymer in which the side groups of the monomers are arranged on the same side of the chain
    • Thermoset: softens on heating, but does not become plastic and moldable

    Definition and Terminology

    • Polymer: a large molecule composed of many smaller molecules (monomers) bonded together
    • Degree of polymerization: the number of monomer units in a polymer chain

    Natural Polymers

    • Biopolymer: includes proteins, cellulose, and silk

    Natural vs Synthetic Polymers

    • Main difference: source of origin (natural: occurs in nature, synthetic: produced by humans)

    Role of Chemists

    • About 80% of today's chemists, including biochemists, work on developing and improving polymers
