In this chapter, we will be learning about polymers. Polymers are large molecules made up of repeating units called monomers. We will explore how polymers are formed through polymerisation reactions, and we will even get to do some activities to understand this process better.
Next, we will study natural rubber. We will learn about its naming, formula structure, and properties. We will also investigate the coagulation of latex, which is the process of turning liquid latex into solid rubber.
Lastly, we will delve into synthetic rubber. We will describe what synthetic rubber is and discuss its uses. We will also compare and contrast the uses of natural and synthetic rubber. By the end of this chapter, we will have a good understanding of polymers, natural rubber, and synthetic rubber.
