#4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles are

Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state‚ the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they

spun into thread and used to make a soft but strong textile. Cotton is a valuable crop because only about 10% of the raw weight is lost in processing. Once natural wax‚ protein‚ and other unnecessary things are removed‚ what’s left is a natural polymer of pure cellulose. Cellulose is the structural component of the cell walls of green plants‚ many forms of algae and the oomycetes. Some species of bacteria separate it to form biofilms. Cellulose is the most common organic compound on Earth. About
