1.1 Polymer The history of polymers goes back further than that of any other group of substances known to mankind. From the origin of mankind in the Garden of Eden, dependence was upon naturally-occurring polymers, for food, clothing, shelter and communication. On the contrary, the history of synthetic polymers is relatively short. It was only through the pioneering work of Staudinger and the quantitative studies of Carothers, the macromolecular concept was accepted. Long before this time, synthetic polymers were being produced and natural polymers were being altered chemically. Styrene was first polymerized in 1839 and in the same year the process of vulcanization of rubber was made successful. 1.2 Description and classification The word polymer was first used to describe compounds with the same composition but of different molecular weights. Berzelius defined polymer as ‘many of a unit’. Carothers defined polymerization as a reaction that is functionally capable of proceeding indefinitely. According to IUPAC, a monomer is defined as ‘a compound, consisting of molecules each of which can provide one or more constitutional units of a polymer or oligomer’ and a monomeric unit or “mer” is the ‘largest constitutional unit contributed by a single monomer molecule in a polymerization processes.

The living/controlled polymerisation techniques opened new vistas in polymer chemistry. The leading authorities in this field and its pioneers contributed chapters to this collective volume. The controlled polymerisation techniques have enabled preparation of polymers, copolymers, and block copolymers with predetermined molecular weights and narrow polydispersity, in which functional groups or biologically active molecules could be placed at well defined locations. They have also enabled preparation of advanced polymeric structures with precisely determined architectures and improved properties. Moreover, they have provided opportunities for preparation of novel polymeric materials from monomers, which before have not been suitable or accessible for such purposes. Properties of some of these polymeric materials may be significantly different from those of the existing ones. They provide opportunities for new applications. Several patents have already been approved for such speciality applications as, drug delivery, biocompatible surfaces, thermoplastic elastomers, moisture curable sealants, and so on. Many more products, based on polymers fabricated by the living/ controlled polymerisation techniques, will certainly emerge in such specialised areas as, nanotechnology, medical devices, "smart polymers", sensors , smart separation technologies, optical fibres and other optical applications, various biomaterials, etc.

Polymers are one of the most fascinating materials of the present era finding their applications in almost every aspects of life. Polymers are either directly available in nature or are chemically synthesized and used depending upon the targeted applications.Advances in polymer science and the introduction of new polymers have resulted in the significant development of polymers with unique properties. Different kinds of polymers have been and will be one of the key in several applications in many of the advanced pharmaceutical research being carried out over the globe. This 4-partset of books contains precisely referenced chapters, emphasizing different kinds of polymers with basic fundamentals and practicality for application in diverse pharmaceutical technologies. The volumes aim at explaining basics of polymers based materials from different resources and their chemistry along with practical applications which present a future direction in the pharmaceutical industry. Each volume offer deep insight into the subject being treated. Volume 1: Structure and Chemistry Volume 2: Processing and Applications Volume 3: Biodegradable Polymers Volume 4: Bioactive and Compatible Synthetic/Hybrid Polymers

Antimicrobial activity was determined to be due to a combination of disulfide-linked nisin, and nisin that was not covalently associated with the PEO-PPO-PEO triblocks. While the extent to which nisin retained antimicrobial activity in its disulfide-linked, copolymer form is not clear, reduction of the nisin-containing copolymer constructs with dithiothreitol demonstrated that nisin released from the copolymer constructs did show antimicrobial activity.
