Polymerization Reactors


INTRODUCTION


Synthetic polymers are synthesized from monomers by a multitude of reaction mechanisms, including addition and step-growth reactions, and polymerization processes (e.g., bulk, solution, precipitation, suspension, emulsion, solid catalyzed polymerization, and interfacial polycondensation). Their macromolecular architecture (e.g., molecular weight distribution, copolymer composition distribution, and branching distribution) depends not only on the chemical nature of the monomers, type of polymerization mechanism, and physical state of the polymerization system but also on the reactor configuration. A variety of polymerization reactors, including continuous (e.g., continuous stirred tanks, train of continuous stirred tank reactors, and loop-type reactors), batch, and semibatch, are commonly employed in polymer manufacturing.

Condensation polymerization releasing small molecules as by-products such as water or methanol. Because this reaction resulting loss of small molecules which is often water, it’s also called dehydration polymerization. Concentrated Sulfuric Acid is used to process to accelerate reaction. Peptide binding and Ester binding is a typical example of condensation polymerization. Ex) polyamide, polyester, urethane, bakelite 

Addition Polymerization Addition polymerization is a reaction, where many monomer bond together via rearrangement of bonds without the loss of any monomers. This occur in different ways which may be through free radical polymerization, cationic polymerization, anionic polymerization andcoordination polymerization. Ex) PVC, polyethylene, polystyrene   Copolymerization Copolymerization is a reaction derives polymer from 2 (or more) monomeric species, as opposed to a homopolymer where only one polymer is used. Common examples of this is a rubber using butadiene and styrene. It's widely used in chemical industry and fiber industry.   Coordination Polymerization Coordination Polymerization is a reaction in which monomer adds to growing macromolecule through an organometallic active center. Coordination type polymers are also stereoregular and can be isotactic or syndiotactic instead of just atactic.   Polymerization     Pros and Cons of Polymerization Polymerization used in industry is classified as follow : bulk polymerization, solution polymerization, suspension polymerization, emulsion polymerization.
