    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.CONDENSATION POLYMERIZATION In condensation polymerization, monomers join to each other producing a small molecule as a byproduct.The small molecule is often water. In this activity, sodium silicate reacts with ethanol in a condensation polymerization, with water as the byproduct.

    Condensation polymerization "Step growth polymerization" and condensation polymerization are two different concepts, not always identical. In fact polyurethane polymerizes with addition polymerization (because its polymerization produces no small molecules), but its reaction mechanism corresponds to a step-growth polymerization. Condensation polymerization is a process that involves repeated condensation reactions between two different bi-functional or tri-functional monomers. Give below in a tabular column is the difference between addition and condensation polymerization.Condensation will be visible on windows, but not usually on walls until the problem is bad or has caused the growth of black mould.

    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. In addition polymerization, two or more molecules of monomers attach together to form a polymer. It is a chain reaction and no byproduct is release. Condensation polymerization on the other hand is a process in which the reaction takes place with a release of a byproduct like water, alcohol, etc. Let's study the latter polymerization in detail.Condensation in a household setting is when airborne water vapour condenses into a liquid and is deposited on interior (or exterior) surfaces.

Condensation (Step-reaction) Polymerization A large number of important and useful polymeric materials are not formed by chain-growth processes involving reactive species such as radicals, but instead by condensation polymerization reactions. These polymerizations often occur with loss of a small-molecule byproduct, such as water or methanol.Condensation forms when the water vapor in the air drops out of suspension and condenses into a liquid form. The colder the air, the more likely it is that water will condense. Condensation forms when warm, humid air comes into contact with a colder surface like your air conditioner’s ductwork.
