The first part of this volume focuses on biosynthesis, metabolism, biodegradation, functions, properties and applications of miscellaneous polymers, such as hemozoin, thymine - containing styrene polymers, polythioesters, polyphosphate, polyhydroxymethionine, polyketides, and natural polyacetals. The second part then goes on to treat the biodegradation of a wide range of synthetic polymers, e.g. substituted cellulose nylon polycarbonate polyvinyl alcohol polyurethanes polystyrenes polyethylene polyanhydrides.
