A Review of Polymer Science by Gowariker, Viswanathan and Sreedhar
Polymer Science is a comprehensive textbook that covers the fundamentals and applications of polymer chemistry and physics. The book was written by Vasant R. Gowariker, N. V. Viswanathan and Jayadev Sreedhar, who are experts in the field of polymer science and technology. The book was first published in 1986 by Wiley and has been reprinted by New Age International.
The book consists of 15 chapters that cover topics such as polymerization, molecular weight and size, chemical and geometrical structure, glass transition temperature, crystallinity, copolymerization, individual polymers, polymer degradation, polymer reactions, polymer solutions, experimental methods, elastomeric, fibre-forming and plastic polymers, and polymer processing. The book also includes a bibliography and an index. The book is written in a clear and concise manner, with numerous examples, diagrams, tables and equations to illustrate the concepts. The book is suitable for undergraduate and postgraduate students of chemistry, chemical engineering, materials science and polymer science, as well as for researchers and professionals in the polymer industry.

Polymer Science is a valuable resource for anyone who wants to learn more about the science and technology of polymers. The book provides a solid foundation for understanding the properties and behavior of polymers, as well as their synthesis, characterization and processing. The book is available as a PDF file from various online sources[^1^] [^2^] [^3^].
In this article, we will review some of the main topics covered in the book Polymer Science by Gowariker, Viswanathan and Sreedhar. We will also highlight some of the key features and benefits of the book for students and teachers of polymer science.
Polymerization
Polymerization is the process of forming polymers from monomers. Polymers are large molecules composed of repeating units called monomers. Polymerization can be classified into two types: chain polymerization and step polymerization. Chain polymerization involves the formation of active centers or radicals that initiate and propagate the polymer chain. Step polymerization involves the condensation or addition of monomers with functional groups that react with each other to form the polymer chain. The book explains the mechanisms, kinetics, thermodynamics and molecular weight distribution of both types of polymerization. The book also discusses the factors that affect the rate and degree of polymerization, such as temperature, pressure, catalysts, inhibitors and solvents.
Molecular Weight and Size
Molecular weight and size are important parameters that determine the properties and performance of polymers. Molecular weight is the mass of a polymer molecule, which can be measured by various methods such as osmometry, viscometry, light scattering and gel permeation chromatography. Molecular size is the spatial extent of a polymer molecule, which can be characterized by parameters such as radius of gyration, end-to-end distance and hydrodynamic volume. The book describes the methods and theories for measuring and calculating the molecular weight and size of polymers. The book also explains the concepts of molecular weight averages, polydispersity index and degree of polymerization.
Chemical and Geometrical Structure
Chemical and geometrical structure are the aspects of polymer structure that relate to the chemical composition and spatial arrangement of atoms in a polymer molecule. Chemical structure refers to the type, number and sequence of monomers in a polymer chain, as well as the presence of any branching, crosslinking or functional groups. Geometrical structure refers to the shape, conformation and configuration of a polymer chain, as well as the orientation and crystallinity of polymer chains in a solid state. The book discusses the various types of chemical and geometrical structures that can exist in polymers, such as linear, branched, cyclic, network, stereoregular, isotactic, syndiotactic, atactic, amorphous and crystalline polymers. The book also illustrates how the chemical and geometrical structures affect the physical and mechanical properties of polymers. 0efd9a6b88
