This book was released on 2010 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is directed towards expanding and refining a free radical multi-component polymerization model. The model considers up to six monomers (unique in the literature), both in bulk and solution polymerization, for either batch or semi-batch reactor modes. As the simulator database contains 13 monomers, 5 initiators, 4 solvents, 3 chain transfer agents and 2 inhibitors, all tested over a wide range of polymerization conditions, from data in both academic and industrial laboratories, several hundred combinations of ingredients can be modeled. The many outputs generated by the model include conversion, molecular weight, polymer composition, branching indicators, sequence length, as well as many others polymerization characteristics related to both production rate and polymer quality. Although the only literature data found to-date contains a maximum of four monomers, model predictions for homo-, co-, ter- and tetra-polymerizations show reasonable agreement against the data at both regular and elevated temperatures. Recently, with the basic polymerization kinetics modeled sufficiently, several expansions to the simulation software have been added. Specifically, depropagation, multiple initiators, back-biting, and composition control have been incorporated and/or improved, each adding to the advancement of the polymerization simulation tool. Depropagation is a vital mechanism that should be accounted for at elevated temperatures. Currently the software has the functionality to implement depropagation but requires further literature resources for improving the kinetic predictions for conversion and polymer composition. Consequently, depropagation research is ongoing. Back-biting and beta-scission of butyl acrylate (BA) is a recent development in free radical polymerization. The completed extension can model BA under the same diverse conditions as the base model, in homo-, co- and ter-polymerizations with depropagation, if applicable. The ability to generate a polymer with a constant (or controlled) composition throughout the reaction has several practical uses. Originally, three composition control scenarios were considered. At present, several methods as well as combinations of methods have been integrated into the model. With these new expansions and the ability to simulate several initiators at the same time, this model is directed towards becoming a complete free radical polymerization tool for training and educational uses both in industry and academia.

This book was released on 2012 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atom transfer radical polymerization (ATRP) is a dynamic technique that possesses tremendous potential for the synthesis of novel polymeric materials not possible through conventional free radical polymerization. However, its use on an industrial scale has been limited by the high level of transition metal complex required. Significant advances have been made in the last 5 years towards lowering the level of copper complexes used in ATRP, resulting in novel variants called "activator regenerated by electron transfer" (ARGET) and "single electron transfer-living radical polymerization" (SET-LRP). To fully realize the potential of ATRP, its use in industrially relevant processes must be studied. Continuous processes such as tubular flow reactors and stirred tank reactors (CSTR) can reduce waste, improve productivity and facilitate process scale-up when compared to common batch reactors. The combination of low copper concentration ATRP techniques and continuous processes are especially attractive towards the design of a commercially viable process. This thesis presents a study into ARGET ATRP and SET-LRP as applied to continuous tubular and stirred tank reactors for the production of acrylic and methacrylic polymers. The equilibrium which governs polymerization rate and control over molecular architecture is studied through batch ARGET ATRP experiments. The improved understanding of ARGET ATRP enabled the reduction of ligand from a 3 to 10 fold excess used previously down to a stoichiometric ratio to copper salts. ARGET ATRP was then adapted to a continuous tubular reactor, as well as to a semi-automated CSTR. The design of the reactors and the effect of reaction conditions such as reducing agent concentration and residence time are discussed. The use of common elemental copper(0) such as copper wire and copper tubing is also investigated with SET-LRP for room temperature polymerization of methyl acrylate. SET-LRP is adapted to a CSTR to observe the effects of residence time on reaction rate, molecular weight control as well as copper consumption rate. The use of copper tubing as a catalyst source for SET-LRP is demonstrated and the design of a continuous tubular reactor using a combination of copper and stainless steel tubing is discussed.
