Practice Other Topics from Synthetic Fibers and Plastics
The topic introduces us to the points that we are going to discuss in the chapter. First, we will learn about synthetic materials and how different they are from natural materials. Then, we will explore the properties of these materials individually.
In this topic, we realise that most of the materials around us are man-made materials, and these materials are made with the help of natural substances. An activity has been given for students to differentiate between natural and man-made materials.
In this chapter, we will explore polymers. A detailed explanation of its definition, a natural polymer, and a semi-synthetic polymer is presented. It also discusses the contribution of Herman Staudinger in the study of a polymer.
The topic discusses synthetic fibres and their properties. It suggests that these fibres are mostly made of petrochemicals, but few are made out of cellulose. Few examples of man-made fibres are also provided.
The topic highlights how and why rayon came into being as a substitute for silk. Rayon is said to be a synthetic fibre manufactured out of cellulose from wood pulp. We will also learn about rayon's properties and uses.
The topic provides knowledge about Polyethylene Terephthalate (PET) that is a thermoplastic polymer. PET can be recycled and is inflammable. Students will learn what happens on burning the PET. Other properties of PET are also highlighted.
The topic elaborates on acrylic and its properties, which is very similar to that of wool. We learn about the uses, advantages, and disadvantages of acrylic. We get to know about its chemical name and other names by which it is known.
