One way of doing this is making really long chains (called polymers) from smaller pieces (monomers); a process which you have probably never heard but surely, in your chemistry class, uses the term addition polymer and condensation polymerization. This article will discuss what condensation polymerization is, how it works and some of the products in which we use them — daily. Ultimately, it will make more sense to you!
Condensation polymerization is a unique process that assembles small molecular building blocks (monomers) to produce large molecules in which individual monomers are joined by bonds made during the formation of water. It can be freed (released) of small molecules like water etc. when these monomers are accumulated to form a polymer. This is the reason we add the word "condensation. Condensing–the term condensation means that something lesser is given up or let go while the greater structure is established.
Types of silicone stopperizationThere are many kinds of condensation polymerizations but the mechanism that they participate in operates through a similar manner. To make this idea clearer, think of just one type of monomer in which the two combining parts look a bit like a carboxylic acid and an alcohol. The polymerization with a second type of monomer such as an amine and acid chloride is the method by which this monomer gets mixed, again with other steric groups. When these two distinct monomers combine, they react chemically. This reaction leads to the formation of a small molecule, such as water. This illustration is a solitary method by which condensation polymerization can occur!
While the chemical transformations involved in condensation polymerization may seem quite daunting to those not versed in organic reactions, we will look at how this works through one among them — polyester. You likely encounter polyester frequently as a material in clothing and packaging. There are 2 types of monomers used to create polyester: a carboxylic acid and an alcohol. These two monomers react together to create a chemical bond called an ester bond.
That reaction takes place when the acid and alcohol meet each other. When these react, they form an ester and water is a side product. That very first one is an esterification reaction. A second monomer is added to this formation which reacts at two sites on the initial reacting element. The addition of these again, results in the release of more water molecules and it, indirectly helps in polymerization of esters to form long chains. An extended version of the process is repeated many times to form a large polymer chain.
Condensation polymers are built from monomers, small building blocks Inside monomers are specific regions of an amphiphilic nature capable of interacting with other monomers to make chains. The choose monomer molecular can change the behavior of the final polymer product to a great extent. One is because you can, for example, use different sorts of monomers and this determines how strong it sort of becomes or whether it is a bit more flexible or if its heat-resistant etc,.
Compared with addition polymerization, condensation polymerization more versatile in terms of properties and use. However, because a small molecule is released in the process of condensation polymerization makes it less useful for producing large amounts of a polymer due to difficulties in controlling the process in an industrial environment.
