Can you imagine a world without plastic, nylon or teflon? All these are synthetic polymers; they are man-made substances that are produced in laboratories under different chemical conditions. Many of the synthetic polymers are obtained from petroleum. In fact, four per cent of the oil produce of the world is used to make plastics that are used in daily life. Some of the synthetic polymers are modelled on existing natural polymers like silk and keratin.
Synthetic polymers are not always environment-friendly. We all know the environmental hazards created by plastics. There is a lot to talk about the harmful effects of synthetic polymers as well and we will deal with that in the later sections.
