This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

Available in PDF, EPUB and Kindle. Book excerpt: The kinetics of the n-butyllithium initiated polymerization of styrene and 1,3-butadiene in ethylbenzene has been studied for the first time under industrially relevant conditions of concentration and temperature. Raman spectroscopy has been used to follow the monomer concentration over a wide range of conversions, and UV spectroscopy to follow the appearance of the propagating live-ends with time. The apparent rate constants for the initiation and propagation reactions in the polymerization of styrene in ethylbenzene have been determined and their activation energies evaluated. The propagation rate constant in the polymerization of I,3-butadiene in ethylbenzene has also been determined. A quantitative study of the livingness of polystyryllithium and polybutadienyllithium live-ends in ethylbenzene at temperatures above 50 has been carried out for the first time, using both UV spectroscopy and viscometry to measure the rate of change of polyanion concentration. It has been shown that polystyryllithium live-ends are more stable than polybutadienyllithium live-ends. A mechanism of chain-transfer to the solvent has been proposed and a comparison with the stability of the live-ends in cyclohexane has been done. Linear homopolymers, linear and star-shaped block copolymers of styrene and 1,3-butadiene are of particular industrial interest and have been synthesized in the present work, and characterized using conventional gel permeation chromatography and differential viscometry. Finally, a modelling package has been used to simulate the effect of feed perturbations on the molecular weight and molecular weight distribution of living polymers synthesized in a continuous stirred tank reactor undergoing periodic feed oscillations. The effect on the dispersity index of the polymer produced of the pulse(s) parameters have been studied and some predictions confirmed experimentally using the alkyllithium initiated polymerization of styrene, that was carried out in a computer controlled continuous flow stirred tank reactor (CSTR).

Available in PDF, EPUB and Kindle. Book excerpt: The thesis describes a study of polymerisation with the intention of demonstrating the generic feasibility of some control techniques for the production of polymers with prescribed molecular weight distributions. The polymerisation of styrene using thermal and catalytic initiation was used as an exemplar for the purposes of developing the strategies. A number of mathematical models have been developed, including the kinetics of the free-radical bulk polymerisation of styrene initiated thermally and by 2,2'azobisisobutyronitrile (AIBN) catalyst without consideration of the environment in which the reactions occur. The dynamics of the polymerisation process are described in terms of the first three moments of the distribution of dead polymer. These moments were used to characterise the molecular weight distribution of the polymer for the purposes of control. Further, the constraints of carrying out the polymerisation in batch and semi-batch reactors, continuous stirred tank reactors and a tubular reactor have been modelled. Dynamic optimisation using Pontryagin's minimum principle and the kinetic model was used to solve the minimum batch time problem by considering separately and simultaneously the two optimal policies, for initiator and temperature. These policies yield the minimum batch time to produce a polymer product which satisfies a set of target specifications for the molecular weight distribution. Using the kinetic and reactor models together, and the optimal temperature policy as a reference level, a model based predictive controller was employed to assess whether a realistic implementation of the policy could be achieved. A difficulty in the practical, real time control of polymerisation is the lack of on-line measurement of molecular weight. A preliminary study of a model based, non-linear observer was conducted to estimate molecular weight distribution on-line. It was shown that the estimate is robust in the face of disturbances and uncertainty in the initial conditions.
