Preface From Cover :
Learning involves acquiring knowledge, which is encouraged in all traditions. For example, the Quran urges people to seek knowledge and to use it for the well being of society:
Knowledge should be applied in a safe, responsible and ethical manner not only to beneit us personally but also to improve the lot of the people we live with. It is also a duty to ensure that our surrounding habitat is not endangered. his sometimes requires knowledge of the local culture to help achieve a desirable outcome.
Chapter 1 in this book is introductory and includes a history of the development of polymers; the importance of the knowledge of materials for engineers and technologists; what makes polymeric materials attractive over conventional materials and a description of the versatile nature of polymers. he subsequent two chapters deal with the polymerisation processes and the processes employed in the conversion of polymeric raw materials into products.
Chapter 4 covers the microstructural features in polymers, including lamellae, spherulites, crosslinking, and the measurements of degrees of crystallinity and molecular orientation. he viscoelastic nature of polymers, the time/temperature sensitivity of viscoelasticity and how this manifests itself in the form of creep, stress relaxation and mechanical damping are covered in Chapter 5. Glass transition and its dependence on
molecular features are also covered in Chapter 5.
