Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

Biopolymer Grafting: Applications presents the latest research and developments in the practical application of these methods in industry, both to enable polymer scientists and engineers to keep up with the latest research trends, as well as to propose ideas for further research and application. Research into bio-based polymers has become increasingly prevalent. However, due to challenges related to the properties of these materials compared to synthetic polymers—such as their resistance to chemicals or weather—uptake has not dramatically increased yet. As a result, improvements in surface modification of bio-polymers through graft copolymerization are enormously important, because they will widen the scope of their applications. Relevant industries for application of these methods include automotive, construction, food, packaging, agriculture, textiles and paper. This book provides an overview of the developments made in the area of biopolymer-based graft polymers. Advantages, disadvantages and suggestions for future works are discussed, assisting materials scientists and researchers in mapping out the future of these new "green" materials through value addition to enhance their use. Helps researchers and product developers understand the applications and limitations of biopolymer copolymers or copolymers of natural polymers Offers a roadmap to future applications development in a range of different industries, including automotive, biomedical and packaging Increases familiarity with a range of biopolymer grafting processes, enabling materials scientists and engineers to improve material properties and widen the range of potential biopolymer applications

The molecules of block and graft copolymers are molecules of a higher order; they consist of homopolymer subchains which are interconnected by chemical valence bonds. This structural com plexity is manifested in the unusual behavior of block and graft copolymers both in solution and in bulk. Many types of interac tions are possible in block and graft copolymers in the solid state. Polymer subchains of one molecule can interact with other polymer subchains which may belong to the same molecule or to different molecules. Since polymer chains of chemically different composition are usually incompatible, thermodynamically unfavorable as well as thermodynamically favorable interactions exist in the solid state. In solutions of block and graft copolymers, the sit uation becomes even more complex, because interactions between the solvent molecules and the various subchains of the copolymer mole cules occur in addition to the interactions between the polymer chains. This multitude of interactions gives rise to a wide spec trum of colloidal and morphological properties which have no paral lel in less complex polymer systems such as homopolymers or random copolymers. Research on the colloidal and morphological behavior of block and graft copolymers is a relatively new field of endeavor. It started in 1954, when F. M. Merrett fractionated mixtures of grafted na tural rubber with the corresponding homopolymers and observed that colloidal sols were formed at certain points during his fractional precipitations.
