Book Description

Iordanskii (Semenov's Institute of Chemical Physics, RAS, Moscow, Russia) collects the work of Russian and Latvian scientists working on the behavior of water in polymers with different hydrophilicity and morphology, covering academic aspects, experimental procedures and approaches, and practical applications. Some specific topics include modeling of anomal diffusion with fitter software, the molecular arrangement of water associated with poly(N-vinyl pyrrolidone) in the first hydrate shell, moisture sorption and its effect on mechanical properties of polymer materials, and the properties and structure of polymeric composite materials obtained from wood hydrolyzed by the method of steam blasting.

Book Description

This book addresses the general aspects of current knowledge of multicomponent transport in hydrophylic and moderately hydrophylic polymers. The first part of the book presents the physical and mathematical models which have been developed in order to predict the behavior of systems consisting of polymer, water and low-molecular solutes. The second half addresses different transport devices for controlled delivery and how the principles reported in the first part could be applied to the regulations of kinetics and the rate of transport of water and solutes. Major applications of polymer systems for controlled release in medicine, agriculture, and in industry are also described.

Book Description

Crude oil production under deep water presents serious operational problems; its main implication is the paraffin blockage with serious economical consequences due to possible obstruction of flow pipes or production lines. Also, there are an increasing number of crude oil fields that produce both crude oil and water, naturally occurred or injected as a second stage recovery to maintain the reservoir operating pressure and fluid flow profile. The water in crude oil emulsion so produced will then be stabilized by the variety of surfactant indigenous to the crude oil called emulsifying agent. It is more economic to separate water before transportation. Polymers have been used extensively in the petroleum industry as pour point depressant and demulsifiers for economical transportation of crude oil since the former can prevent the deposition in the pipe lines which may cause blockage of the transportation lines. Demulsifiers are class of surfactants used to destabilize the emulsions by reducing the interfacial tension at the emulsion interface, often by neutralizing the effect of the other, naturally occurring surfactants which are stabilizing the emulsion.

Book Description

Although several monographs and reviews have appeared on individual polymers of this type, and their applications and other technical aspects have also been discussed, this is apparently the first book to deal with the physical chemistry of water-soluble synthetic polymers as a group. This collective survey enables their properties and behaviour to be compared, and to be correlated with their molecular structures for predictive purposes. However, this has made it necessary to critically re-appraise much of the earlier fundamental work, so that current discussion of more recent work can be put on ta proper basis. Thus, of the 1800 or so references cited, the middle two-thirds related to the twenty-year period centred on about 1968. Nevertheless, sufficient key recent references have also been included so that the existing ‘state of the art is delineated.

Book Description

The chapters in this book are based upon lectures given at the NATO Advanced Study Institute on Synthetic Membranes (June 26-July 8, 1983, Alcabideche, Portugal), which provided an integrated presentation of syn thetic membrane science and technology in three broad areas. Currently available membrane formation mechanisms are reviewed, as well as the manner in which synthesis conditions can be controlled to achieve desired membrane structures. Membrane performance in a specific separa tionprocess involves complex phenomena, the understanding of which re quires a multidisciplinary approach encompassing polymer chemistry, phys ical chemistry, and chemical engineering. Progress toward a global understanding of membrane phenomena is described in chapters on the principles of membrane transport. The chapters on membrane processes and applications highlight both established and emerging membrane processes, and elucidate their myriad applications. It is our hope that this book will be an enduring, comprehensive compen dium of the state of knowledge in the field of synthetic membranes. We have been encouraged in that hope by numerous expressions of interest in the book, coming from a variety of potential users.
