Experiment No.16: Kinetics of Condensation Polymerization (5/02/18) Abstract: The kinetics of a condensation polymerization reaction between adipic acid and ethylene glycol is to be studied in a batch reactor at 180° C. The method applied to find the kinetic parameters is the differential method. The following examples of condensation polymers are illustrative. radical polymerization (ethylene, vinylchloride, styrene, butadiene) by coordi-nation polymerization (ethylene, propylene, butadiene) and by condensation or addition polymerization (polyesters, polyurethanes, formaldehyde resins). A condensation polymerization is a form of step-growth polymerization in which monomers and/or oligomers react with each other to form larger structural units while releasing smaller molecules as a byproduct such as water or methanol. Also, the polymerization reactions for Nylon 6 and Spandex do not proceed by elimination of water or other small molecules. 1.3 Methods of Polymerization Polymerization reactions are highly exothermic reactions, producing a large Condensation Polymerization S Ramakrishnan S Ramakrishnan is a professor in the Department of Inorganic and Physical Chemistry at the Indian Institute of Science. Kinetics of Condensation Polymerization-Preparation of a Polyester. The silica-based materials are sometimes synthesized without a good understanding of the underlying reaction kinetics. Chain-growth mechanism 4. Principles of Condensation Polymerization. D. C. Polymer synthesis 3 • Polymers may be formed by two major kinetic schemes. The kinetic treatment of condensation polymerization focuses on the step‐growth mechanism, with a separate section devoted to cases of living polycondensation. 1.Step polymerization 2.Chain polymerization (Faster) • Free radical polymerization Initiation Propagation Termination • Anionic polymerization • Cationic polymerization 4. Combining macromolecular kinet­ ics with reactor and process design has led to a new concept called reac­ tion engineering. Process Improvements and Polymerization Kinetics Process Technology. Weight-fraction distribution in a linear condensation polymer for several extents of reaction p (ref. Recent advances in controlled polymerization techniques have offered the possibility to change the growth mechanism to a “living” polymerization in both cases of polymerization. 2).
