Polymerisation reactions involve the gradual addition of smaller molecules or monomers to form larger polymers. These polymers can be natural, such as collagen in skin and hair, or synthetic, such as plastics and fibers. There are several types of polymerisation reactions, each with its unique characteristics.
Homopolymerisation: In a homopolymerisation reaction, identical monomers join together to form larger molecules. This is the most common type of polymerisation and is responsible for the formation of plastics, rubber, and other synthetic materials.
Copolymerisation: In a copolymerisation reaction, two or more different monomers combine to form a larger polymer. This type of polymerisation is responsible for the formation of natural polymers like cellulose and silk.
Hybrid Polymerisation: A hybrid polymerisation reaction combines features of both homopolymerisation and copolymerisation. For example, in the polymerisation of polystyrene, styrene monomers join together to form larger molecules, but the polymer contains both repeating units of styrene and repeating units of other monomers.
Chain Polymerisation: This is a process where a single polymer molecule is synthesised from a chain of smaller molecules called monomers. Each monomer joins to the growing polymer chain, and the reaction continues until a single polymer molecule is formed.
Condensation Polymerisation: In a condensation polymerisation reaction, two or more molecules with functional groups join together to form a larger molecule. This type of polymerisation is responsible for the formation of proteins, lipids, and other biopolymers
