Polymers form an important family of materials. (a) There are three main sub-groups of engineering polymers with distinct differences in their structures. Name these sub- groups; describe their structural differences and bonding mechanisms. (b) Explain how the structural differences between the three main sub-groups of engineering polymers affect the physical and mechanical properties of the polymers. Use simple diagrams to illustrate your answer. Include examples and applications of specific polymers for each sub-group.
