G. Bhat, V. Kandagor, in Advances in Filament Yarn Spinning of Textiles and Polymers, Condensation polymerization. Polycondensation is the term used to describe polymers formed as a result of reactions involving the condensation of organic materials in which small molecules are split out. In condensation polymerization, molecules of monomer and/or lower . Get this from a library!

Insertion polymerizations allow the synthesis of highly stereoregular polymers. Reactors and agitators affect not only rates of polymerization, space‐time yields, and residence times but also polymer structures and molecular weight distributions. The heart of the polymerization plant is the polymerization reactor or a group of reactors. Polycondensation at room temperature between two or more fast-reacting intermediates is becoming widely used because of its convenience and speed. The interfacial polycondensation system, in particular, which employs two immiscible liquids, is applicable to a wide variety of chemical structures: amides, urethanes, esters, sulfonates. Description; Chapters; Supplementary; Over the last twenty years, the field of the chemistry of polymerization witnessed enormous growth through the development of new concepts, catalysts, processes etc. Examples are: non classical living polymerizations (group transfer polymerization, living carbocationic polymerization, living radical polymerization and . In chemical compounds, polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and their inherent steric more straightforward polymerizations, alkenes form polymers through relatively simple radical reactions; in contrast, reactions involving substitution at a carbonyl group require more .
Particular emphasis is laid on the role of cyclization reactions. Special categories of polycondensation processes are discussed in more detail: syntheses of hyperbranched and multicyclic polymers, non-stoichiometric polycondensations, interfacial polycondensations, solid state polycondensations, condensative chain polymerizations etc. This book reports on origin and history of polycondensation chemistry beginning in the first half of the 19th century. Furthermore, history and inventors of the most important polycondensates Author: Hans R Kricheldorf. Polycondensation, in which water is always a product, is endothermic, in contrast to other classical polymerization reactions. Shifting the chemical equilibrium of the reversible reaction to the side of the polyester requires that the water produced by the condensation reaction is continuously removed from the reaction mixture. A nonlinear reduced-order state observer is applied to estimate the degree of polymerization in a series of polycondensation reactors. The finishing stage of polyethylene terephthalate synthesis is considered in this work. This process has a special structure of lower block triangular form, which is properly utilized to facilitate the calculation of the state-dependent gain in the observer by: 4.
