WebNatural polymers include such materials as silk, shellac, bitumen, rubber, and cellulose. However, the majority of polymers or plastics used for engineering design are synthetic and often they are specifically formulated or “designed” by chemists or chemical engineers to serve a specific purpose. WebA polymer is a large molecule also called macromolecule, composed of repeating structural units typically connected by covalent chemical bonds. 3 Polymer Synthesis Is the process of combining many small molecules …

WebClassification of Polymers: There are several ways of classification of polymers based on some special considerations. Based on Source: Under this type of classification, there… Webconducting polymers The result is a class of polymers that can be oxidized or reduced more easily and more reversibly than conventional polymers. The effect of this oxidation or reduction on polymer is called doping, i. e. convert an insulating polymer to conducting one. book cutting board
