1.PLASTIC MATERIALS: In general, plastic materials are a normal part of everyday life. They also play important roles in sectors such packaging, telecommunications, transport, construction, medicine, agriculture and information technology. Plastics consist of long chains of molecules, mostly made of the element “carbon”. These chains of macromolecules are called polymers, which is another name for plastics. Polymers are composed of smaller molecules called monomers. 1.1 THE ORIGIN OF PLASTICS:
