DOWNLOAD EBOOKThe policy adopted in Volume 1 of this series of including a relatively small number of topics for detailed review has been continued here. The techniques selected have received considerable attention in recent years. F or this reason and because of the significance of the characterisation data, further coverage of 13C nuclear magnetic resonance spectroscopy and small angle neutron scattering is given in the first two chapters. In Chapter I a large part of the review describes the determination of monomer sequence distributions and configurational sequences in copolymers formed from more than one polymerisable monomer. The review on neutron scattering (Chapter 2) is directed towards the determination of the chain conformation in semi-crystaIIine polymers, which has provided important results for the interpretation of chain folding and morphology in crystaIIisable polymers. Laser Raman spectroscopy has also been used for morphological studies, and this application together with a description of the theoretical and experimental aspects of the technique is given in Chapter 3. X-ray photoelectron spectroscopy because of its extreme sensitivity to surface characteristics has provided information on polymeric solids that could not be obtained by other techniques. The principles and practice of this ESCA technique, including its use for simple elemental analysis, structural elucidation and depth profiling, are described in Chapter 4. The final two chapters are mainly concerned with the chain conformation of polymers in dilute solution. Ultrasonic techniques (Chapter 5) show pmmise for observing the dynamics of conformational changes.

DOWNLOAD EBOOKChemical modification of polymers by reactive modifiers is no longer an academic curiosity but a commercial reality that has delivered a diverse range of speciality materials for niche markets: reactively grafted styrenic alloys, maleated polyolefins, super-tough nylons, silane modified and moisture-cured polyolefins, and thermoplastic elastomers, are but few exam ples of commercial successes. Although the approach of reactive modification of polymers has been largely achieved either in solution or in the solid state (through in situ reactions in polymer melts), it is the latter route that has attracted most attention in the last two decades owing to its flexibility and cost-effective ness. This route, referred to as reactive processing, focuses on the use of suitable reactive modifier(s) and the adoption of conventional polymer processing machinery, an extruder or a mixer, as a chemical reactor, to perform in situ targeted reactions for chemical modification of preformed polymers. This relatively simple, though scientifically highly challenging, approach to reactive modification offers unique opportunities in exploiting various reactive modifiers for the purpose of altering and transforming in a controlled manner the properties of preformed commercial polymers into new/speciality materials with tailor-made properties and custom-designed performance for target applications. Such an economically attractive route constitutes a radical diversion away from the traditional practices of manufacturing new polymers from monomers which involves massive in vestments in sophisticated technologies and chemical plants.

DOWNLOAD EBOOKFlexible polyurenthane foams of all types are a unique group of plastics materials, characterized by the fact that a multitude of different sets of properties can be obtained by varying the levels of a relatively small number of base components in the formulations. Different foam grades, primarily characterized by density and hardness, can be obtained by changing the ratio between base polyol, polymer polyol, water, blowing agent, isocyanate and other components. It is not uncommon for foam producers in industrialized countries to manufacture more than one hundred different foam grades based on these basic chemicals, plus the ancillary chemicals needed for optimized processing. This has always made flexible polyurethane foams a highly suitable candidate for correlating these variations in the formulations with the resulting properties in a mathematical way, aimed at predicting the properties as accurately as possible, fine-tuning existing grades or designing new foam grades. This book discusses the methodology for obtaining meaningful equations for correlating properties with formulation variables and other influencing factors
