Polymerisation is the process by which monomers are converted into polymers. Both polymers and macromolecules are high molecular mass substances but still they have one important difference. For example, polythene and chlorophyll are macro molecules but polythene alone is a polymer because it has a repeating structural unit. Polymers are classified on the basis of structure, synthesis and molecular force existing between the polymer molecules. The polymer melmac is obtained by (a) addition melmac is obtained by (b) condensation polymerization of melamine and formaldehyde (c) coordination polymerization of melamine (d) step growth polymerization of caprolactum

Key Concepts

Polymerization

Polymerization is the chemical process in which small molecules known as monomers are joined together to form larger macromolecules or polymers. This process is fundamental in forming various materials with distinct physical properties and involves specific mechanisms that dictate the structure and characteristics of the resulting polymer.

Monomers

Monomers are the basic building blocks in polymer chemistry. They are small, often multifunctional molecules that can react with one another through chemical bonds to produce long-chain macromolecules. The ability of monomers to link repetitively is crucial to achieving the defined structures seen in polymers.

Polymer Structure

A key aspect of polymers is their repeating structural units, which dictate both the physical and chemical properties of the material. This regularity in structure distinguishes polymers from other macromolecules that may not exhibit such repetition, affecting their behavior and applications.

Types of Polymerization Processes

Polymerization can occur via several mechanisms, including addition polymerization, condensation polymerization, coordination polymerization, and step-growth polymerization. Each of these methods involves different processes, reaction conditions, and types of bonding that lead to varied polymer structures and functionalities.

Condensation Polymerization

Condensation polymerization is a process where monomers join together with the simultaneous elimination of a small molecule, such as water or methanol. This method is often used to produce polymers with complex structures, and the reaction conditions must be carefully controlled to achieve high molecular weight products.
