The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization. The process of formation of polymers is called polymerization.The chemical and physical properties of a polymer mainly depend on the type of monomer or monomers used to form the polymer. Click here to navigate to parent product. There is a loss of some simple molecules such as water and alcohol due to the condensation mechanism. Which of the byproduct molecule is released in the formation of polyurea? Condensation Polymerization. First Published 2017. Condensation polymerization is a polymerization process characterization by the repeated elimination of simple molecules. II. Loss of each kind of functional group in each step for bifunctional species Chain-reaction polymerization is also known as Addition, while step-reactions are often called Condensation. They have a very high melting point. 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. The monomers in this case have two reactive groups. c) ester and alcohol Polymerization and polycondensation reactions Main characteristics and stages. Please enable Cookies and reload the page. Some of the main characteristics of this type of polymerization are; 1. Always accompanied by the release of a byproduct molecule Polymers are the macromolecules formed by linking of a large number of small units called monomers through chemical reactions. Polymerization and polycondensation reactions Main characteristics and stages. b) H2O Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. 1. Condensation polymerization definition is - polymerization in which a single molecule is eliminated —distinguished from addition polymerization. Film condensation.In film condensation, the condensate wets the surface and forms a liquid film on the surface that slides down under the influence of gravity.Film condensation results in low heat transfer rates as the film of condensate impedes the heat transfer. 3. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water. Among them are: DNA , starch , silk and cellulose . An example of a condensation reaction is the esterification of carboxylic acids with alcohols. 1 In the case of a condensation reaction, two monomers combine with the loss of a small molecule, usually an alcohol, a water or an acid molecule, whereas an addition reaction involves only the rearrangement of the electrons of a double bond to form a single bond with another molecule. Give below in a tabular column is the difference between addition and condensation polymerization. -Polyamide: Used to make Kevlar due to its rigid organized fibers.-Polybutadiene: Used in the sidewall of truck tires due to its toughness.-Neoprene: Used in surgical and dental gloves due to its flexible nature. Find 2 Answers & Solutions for the question What are the molecular elements for condensation polymerization? Book Plastics Technology Handbook. Consider a reaction of polymer formation by condensation polymerization, completed in n-steps, with the liberation of a certain byproduct. c) n-1 Only-C-C-linkages Present In The Polymer Structure II. Condensation polymers form: when bifunctional monomers react to form a long chain polymer molecule; small molecules, such as water, are eliminated during the reaction; Polyesters, polyamides, proteins and polysaccharides such as cellulose, are all examples of condensation polymers. Characteristics of Polymers and Polymerization Processes book. Click here to navigate to parent product. a) HCl a) 2n These assessments will test you on the following aspects of condensation: View Answer, 2. Characteristics of Condensation Polymers Condensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight. Two main characteristics of Condensation Polymerization Instead of double bonds, these monomers have functional groups (like alcohol, amine, or carboxylic acid groups).
