condensation polymerization takesplace in a step wise manner.In addition polymerization monomers react to form polymers and there is no biproduct formation.In condesation polymerisation, byproducts are formed in every steps called as dimer,trimer.tetramer etc...
Proteins are formed by step-growth polymerization. This happens in the ribosomes.
The general term is "polymerization reactions." The main types of polymerization reactions are condensation reactions (a small molecule is lost at each step) or addition reactions (no molecule is lost at each step). Each of these is then further subdivided into categories depending on the specific chemistry that's involved.
Chain termination is any chemical reaction leading to the destruction of a reactive intermediate in a chain propagation step in the course of a polymerization, effectively bringing it to a halt.
Step-growth polymerizationChain-growth polymerizationGrowth throughout matrixGrowth by addition of monomer only at one end of chainRapid loss of monomer early in the reactionSome monomer remains even at long reaction timesSame mechanism throughoutDifferent mechanisms operate at different stages of reaction (i.e. Initiation, propagation and termination)Average molecular weight increases slowly at low conversion and high extents of reaction are required to obtain high chain lengthMolar mass of backbone chain increases rapidly at early stage and remains approximately the same throughout the polymerizationEnds remain active (no termination)Chains not active after terminationNo initiator necessaryInitiator required
Acts as a chain intiatoor by breaking into two benzoyl chloride free radicals (homolytic cleavage) and then involves itself in chain propoogation step after breaking free in the initial step known as the chain initiation step.
the structural unit of step reaction polymerization are chemically identical to the monomer employed in the reaction while those of the chain reaction may or may not be identical addition or step polymers take their names from their starting monomers while those of the chain reaction is not so
chain-growth and step-growth polymerization reactions build polymer chains from monomers.By processing i understand the degradation of these polymers into monomers.

Polymerization describes the formation of of large molecules (polymers) with repeating structure from smaller molecules (monomers) . The word polymer comes from Greek words meaning many (poly-) and parts (-mer). Many of the resulting molecules are plastics, so polymer is occasionally used in place of the word plastic, though this is not an accurate usage. Polymerization is an all-encompassing term that describes formation of polymers by any method.There are two main types of polymerization; addition polymerization and condensation polymerization. Addition polymerization creates larger molecules by opening up double bonds on the smaller molecules (monomers). These opened-up bonds react with parts of other monomers (single part) to form dimers (double part). This reaction can repeat to add another molecule to for a trimer (three part). This continues until you obtain the right size molecule and you stop the reaction. Addition polymerixation can occur using a single type of monomer. There are no by products of the reaction except the longer chain molecules (polymers).In condensation polymerization, two monomers of different types are used. They have different types of reactive (or functional) groups on them. A reaction between monomer A and monomer B results in a dimer, plus another small molecule (often water) that is not part of the polymer. To create long polymers the monomers must have reactive groups on both ends or a chain cannot be formed.Polymerization is an all-encompassing term for creating polymers by any method. Condensation Polymerization is a term denoting a specific type of reaction for creating polymers.
Polymerization is duel monsters card (in YU-GI-OH) which allows the duelist to combine two duel monsters to make a stronger monster.
Condensation converts gas back to water. It is 2nd step of water cycle.
Condensation happens after water is evaporated. It is the reverse process of evaporation.
