Addition polymerization is when the monomer molecules bond to each other without the loss of any other atoms. In addition polymerization, Lewis bases or acids, or Radical initiators act as catalyst, whereas condensation polymerisation, mineral bases or acids act as a catalyst. Chain growth polymerization (American spelling) or chain-growth polymerisation (English spelling) is a polymerization technique where unsaturated monomer molecules add onto the active site on a growing polymer chain one at a time. An addition reaction is one in which two or more molecules join together to give a single product. There are two methods by which polymers are made: Addition polymerisation Condensation polymerisation In addition polymerisation, alkenes add to themselves. Page 1 of 1 - About 9 essays. Looks like you’ve clipped this slide to already. Author: Created by ellenderr. In addition polymerization, monomers react to form a polymer without the formation of by-products. Addition polymerisation is the name given to a chemical reaction in which unsaturated monomers are joined, forming a polymer. See our User Agreement and Privacy Policy. 1.1.1 Addition Polymerization In addition polymerization (sometimes called chain-growth polymerization), a chain reaction adds new monomer units to the growing polymer molecule one at a time through double or triple bonds in the monomer. Created: May 4, 2016. The reaction is shown in the graphic on the left. Chain addition polymerization takes place by repeated additions of monomers to the growing polymer chain. large molecule or a macromolecule which essentially is a combination of many subunits Addition polymerization definition is - polymerization without formation of a by-product —distinguished from condensation polymerization.

They are: • Addition or chain polymerization • Condensation or step polymerization Introduction to Polymers 12 13. In addition polymerization, electrons from a double-bond are used to form bonds between other monomers, like in the process used to make polyethylene. by addition polymerization triggered by free radicals or ions or by con­ densation, coupling, ring-opening, or ring-closing reactions. 10.5 Polymerization Chemistry 30 PPT.

SOLUTION POLYMERIZATION After the reaction is over, the polymer is used as such in the form of polymer solution or the polymer is isolated by evaporating the solvent.  Polymer so formed can be used for surface coating. This is sometimes referred to as vinyl or chain polymerization ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 25f112-ZDc1Z Oligomers are formed at the beginning and are later combined together, forming the polymer chain. WJEC Chemistry. The polymerization process takes place in three distinct steps: 1. Addition polymerisation produces the addition polymers by the addition of olefinic monomers, whereas the condensation produces the condensed polymers by the condensation of two different monomers. Mechanism of Addition Polymerization Polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks.There are many forms of polymerization and different systems exist to categorize them. Monomers exist throughout the reaction, its concentration decreases steadily with time.  It is used for the production of Polyacrylonitrile, PVC, Polyacrylic acid, Polyacrylamide, Polyvinyl alcohol, PMMA, Polybutadiene, etc These reactions involve the addition of many single “subunits” together to … Summary presentation about addition polymerisation. Under low temperature condition, small amount of PM was formed from benzene-N2 mixture without oxygen. As this addition proceeds further a long molecular chain is formed. Other Addition Polymers.

Polymerization, Isobutyl Rubber Synthesis, Polyvinyl Ethers Cationic Polymerization Some differences between cationic and anionic polymerization • Rates are faster for cationic (1 or more orders of magnitude faster than anionic or free radical) • is very reactive, difficult to … Addition polymerizations usually are carried out in the presence of catalysts, which in certain cases exert control over structural details that have important effects on the properties of the polymer. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water.
