Polymers, high molecular weight compounds, have most essential position in the materials field today even though have been introduction in meaning full logic more recently. In performance, characteristics, and application predictions, polymers offer novelty and usefulness not to be found in other kinds of materials. The rapidity of the all-round developments in polymer science and technology and the unique pace of application development and developments in the design of products and parts and components of polymer processing equipment necessitate fresh efforts in organizing old and established thoughts, ideas, concepts, and practices and updating them in the light of the latest unfolding polymer. Polymer constitutes a diverse range of light-and energy-efficient materials discovered and developed in a large measure out of the sheer necessity of meeting the growing needs and demands of our higher-profile society. The present level of sophistication, growth, and advancements of our expanding society has been made possible in a large measure through continued imaginative and creative efforts of scientists, engineers, and technologists in the polymer field. In recent years there is a considerable demand for specialty supplies, and there is an increasing affinity to design “intelligent polymers,” ie, specialty polymers, which extend the scope of polymeric materials. Natural polymers have been used throughout the ages. From the beginning man has depended upon animal and vegetable matter for nutrition, shelter, warmth, and other requirements and desires. It is utilized in the field of pharmacology, diagnosis, and artificial respiration and in creation of articles of patient care. Commercially accessible synthetic polymeric materials are long lasting and have noble mechanical properties such as tensile strength and abrasion resistance, but because of the lack of functional groups in them, they resist dyeing and resist chemical reactions. The properties can be further improved by introducing various functional groups into their molecules. This ranges the scope of polymeric materials. Efforts have been made to use readily available natural polymers such as cellulose, proteins, gums and rubber, etc., for making polymers better properties. Copolymerization is an important method for the modification of polymers. Copolymerization is defined as “a process in which two or more structurally different monomers are incorporated into the same polymeric chain.” The properties of polymer produced by copolymerization can be varied over a wide range by adjusting the monomer ratio. Copolymerization involves a chemical reaction between two or more different monomers, which results the formation of following different types of copolymers.
