Sep 16, 2017· Condensation polymers are any kind of polymers formed through a condensation reaction—where molecules join together—losing small molecules as byproducts such as water or methanol, as opposed to addition polymers which involve the reaction of unsat.
Class XII Chapter 15 – Polymers Chemistry Question 15.8: How can you differentiate between addition and condensation polymerisation? Answer Addition polymerization is the process of repeated addition of monomers, possessing double or triple bonds to form polymers. For example, polythene is formed by addition polymerization of ethene.

Other articles where Condensation polymerization is discussed: monomer: Condensation polymerizations are typical of monomers containing two or more reactive atomic groupings; for example, a compound that is both an alcohol and an acid can undergo repetitive ester formation involving the alcohol group of each molecule with the acid group of the next, to…
Jun 24, 2009· Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule.
Condensation Polymerisation. Condensation polymerisation involves a reaction between monomers with two different functional groups. When these types of monomers react they join together, usually losing a small molecule such as water, and so the reactions are called condensation reactions.

Condensation polymers form from the step growth polymerization. Here when molecules of monomers react to form a bond they replace certain molecules. These molecules are the by-product of the reaction. In most cases, this by-product is a water molecule. The type of polymers that result from a condensation polymerization depends on the monomers.
Characteristics of Condensation Polymers. Condensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight. 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.

Polymers and properties of polymers are a chunky topic in the GCSE chemistry syllabus. You have to know about the uses of polymers as well as their chemical structures. From monomers to polymers in the process of polymerisation is where this topic usually begins, before other aspects such as thermosoftening and thermosetting polymers are covered.
