POLYMERS Introduction to Polymers Some Applications of Polymers • Properties of Polymers Introduction to Polymers Polymer is a large molecule composed of repeating small molecule units. The term "polymer" was derived from the Greek words poly and meros, which means many and parts, respectively. We often associate polymers with the term plastics. In reality, these plastics are just some examples of synthetic polymers commonly encountered and used daily such as grocery bags and water bottles. The small molecule precursor or building block of polymers is called a monomer. For example, polyethylene which is commonly used in pipes, cable coverings, and toys is derived from ethene (Fig. 7.1a). Often, the chemical structure of polymers is represented by the monomer enclosed in a parenthesis (Fig 7.1b). The number of repeating monomer units is represented by the subscript n. Monomer Polymer H н H H н un Ethene Polyethylene (a) (b) Figure 7.1. Monomer ethene (a) and chemical structure of polyethylene (b). Some Applications of Polymers 1. Natural polymers such as proteins, nucleic acids, and polysaccharides serve as the basic functional unit of plant and animal life. 2. Natural polymers present in meat, vegetables, and rice serve as food. 3. Polymers can be used as construction materials specifically as concrete, and insulation. 4. Polymers can be crafted into light materials for transportation such as in aircrafts, automobiles, ships, and trucks. 5. Polymers can be used as packaging materials such as food and water containers. ↑
