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

What is the reaction that links monomers to form a chain?
Addition polymer
What chemical reaction formed these large molecules?
Large organic molecules (macromolecules) are generally formed by condensation reactions between smaller molecules.Condensation means that a small molecule is formed from the atoms removed during the reaction. In cells, the small molecule is water, so the type of condensation reaction is dehydration.Examples:glucose + (chain of n glucose residues) forms chain of n + 1 residues + wateramino acid + (chain of n amino acid residues) forms chain of n + 1 residues + water
What is chain termination?
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.
What is concentration polymerization?
If you're talking about condensation polymerization, it is a reaction in which monomers join together to give a long chain molecule (the polymer) and a small molecule, usually water or hydrochloric acid, like Nylon.
Why use water in polymerase chain reaction?
The enzyme polymerase is functional in water medium, that's why water is needed. Do understand that biological polymerization reactions as in nucleic acids and other molecules, are condensation reaction (dehydration synthesis) where water is liberated.
What are the differences between additional polymerization and condensation polymerization?
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
What is the reaction that links monomers to form a chain?
Addition polymer
What is the name for a reaction that links monomers to form a food chain?
Dehydration synthesis is the name for a reaction that links monomers to form a chain.
What reaction adds monomers to a growing polymer chain?
Such reactions are known as polymerization processes, they are of two types 1- addition polymerization and 2- condensation polymerization.
What is the name of a reaction that links monomers to form a chain?
Polymerization .

What are the similarities between addition polymerization and condensation polymerization?
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.
Differences between amino acids are normally due to differences in which part of the molecule?
The R-side (variable) chain
What is the duration of The Chain Reaction?
The duration of The Chain Reaction is 1.53 hours.
