Polymers are a large class of materials consisting of many small molecules. Polymers such as cotton, wool, rubber, Teflon(tm), and all plastics are used in nearly every industry. Evidence for the existence of cellulose comes from the close match of an infrared absorption spectrum of celestial origin with that of cellulose. The surface film is a pellicle of cellulose. In most elastic materials, such as metals used in springs, the elastic behavior is caused by bond distortions. In its relaxed state, rubber consists of long, coiled-up polymer chains that are interlinked at a few points. Polymeric delivery systems are mainly intended to achieve controlled or sustained drug delivery. Targeting of drugs to the colon following oral administration has also been accomplished by using polysaccharides. Polymeric materials have a vast potential for exciting new applications in the foreseeable future. Polymer uses are being developed in such diverse areas.
