A. Polymerisation: Polymerisation is a chemical process in which small molecules, known as monomers, combine chemically to form larger, more complex structures called polymers. This process can occur through various mechanisms, including addition (chain-growth) polymerisation and condensation (step-growth) polymerisation. Polymers have a wide range of applications in materials science, biology, and industry, as they can possess unique physical and chemical properties.
B. Monomers: Monomers are small, simple molecules that serve as the building blocks for polymers. They can be identical (homopolymers) or different (copolymers) in structure. Monomers undergo polymerisation to form larger chains or networks, creating materials with diverse properties. Common examples of monomers include ethylene (which can form polyethylene) and styrene (which can form polystyrene).
