Modified Polymers, Their Preparation and Properties brings together the main lectures presented at the Fourth Bratislava Conference on Polymers held in Bratislava, Czechoslovakia, on July 1-4, 1975. Contributors explore the properties of modified polymers and their preparation, covering topics ranging from radiation crosslinking of polyvinyl chloride (PVC) with ethylene glycol dimethacrylate to chemical modification of polymers and the influence of chemical structure on the properties of polymers. This book is comprised of eight chapters and begins with a discussion on crosslinking of PVC in the presence of ethylene glycol dimethacrylate, studied by microcalorimetry, electron spin resonance, and structure investigation. The next chapter examines some characteristic features of chemical transformations of polymers on three examples: reactions of various organo-lithium bases onto the ester carbonyls of polymethylmethacrylate (PMMA); reaction of phenyl-lithium onto the carbonyl groups of PMMA; and chemical modification of polyvinylalcohol by metallation and subsequent reactions of alkylhalides or of propane sulfone. Subsequent chapters focus on how chemical structure affects polymer properties; alternating copolymer graft copolymers; acrylonitrile block and graft copolymers; and problems of polymer modification and the reactivity of functional groups of macromolecules. The final chapter is devoted to the separation and characterization of block and graft copolymers by thin-layer chromatography. This monograph will be a valuable source of information for chemists.

There is little question today that processes of globalization affect national and local economies, governance processes, and conditions for economic competitiveness in the major urban regions of the world. In most liberal-democratic countries, these processes are occurring according to a rationale which attempts to combine strategies of state-supported development with increasing local-regional governmental decentralization and autonomy. Against this background, the issue of metropolitan development is being redefined worldwide, along with its institutional frameworks, modes of governance, policy instruments, and spatial planning strategies. The overarching assumption of this volume is that 鈥榤etropolitan space鈥? far from being consolidated as a policy object, is currently being redefined and in some instances 鈥榗onstructed鈥?and contested as a scale, through a variety of policy practices related to spatial-economic development objectives. Through case studies drawn from across four continents, the authors reveal a range of interesting cross-national commonalities concerning the power that state actors, situated at various spatial scales, exert as agents in these processes. This volume interrogates key research issues raised by these developments, and is intended as a contribution to the establishment of a globally comparative analysis of the construction of metropolitan spaces and scales under conditions of globalization and neoliberalization.
