The reaction is a condensation polymerisation nH 2 N(CH 2)6NH 2 + nClOC(CH 2) 8 COCl â H 2 N[(CH 2)6NHCO(CH 2) 8]nCOCl + nHCl The nylon formed is nylon 6â10 so called because of the lengths of the carbon chains of the monomers. The second condensation polymerization you will carry out is a reaction between phenol and formaldehyde to produce a polymer known as Bakelite (see mechanism at the top of the next page). The byproducts formed may be water or hydrogen chloride. Bakelund performed this synthesis at the beginning of the twentieth century, producing the first synthetic polymer. Polyester and nylon are some of the most common examples of this type. In condensation polymerization, molecules of monomer and/or lower molecular weight polymers chemically combine, producing longer chains that are much higher in molecular weight. In these cases the reactor must supply heat in order to maintain a practical reaction rate. Condensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight. In chemistry of industrial polymers: Industrial polymerization methods. Step-growth polymerizations can be divided into two lasses: condensation and addition polymerization. Condensation Polymerization S Ramakrishnan S Ramakrishnan is a professor in the Department of Inorganic and Physical Chemistry at the Indian Institute of Science. Polyamide and proteins are examples of condensation polymers. However, in condensation polymerisation, the monomers do not need a C=C double bond ⦠Condensation Polymerization. In condensation polymerization, the formation of the polymer occurs when there is a loss of some small molecules as byproducts through the reaction where molecules are joined together. The diamine is present in excess to react with the hydrogen chloride that is eliminated. Get more information in the following paragraphs. Recent advances in controlled polymerization techniques have offered the possibility to change the growth mechanism to a âlivingâ polymerization in both cases of polymerization. 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. The polymers usually formed by this mechanism have two functional groups, where functionality is defined as the average number of reacting groups per reacting molecule. In this article, we are going to discuss condensation type of polymerization. The initiation mechanism is explained by an autoxidation to an active ketohydroperoxide form. Condensation polymerization, on the other hand, is endothermicâthat is, the reaction requires an input of heat from an external source. Polymerization is of two types, condensation polymerization and addition polymerization. 1 In the case of a condensation reaction, two monomers combine with the loss of a small molecule, usually an alcohol, a water or an acid molecule, whereas an addition reaction involves only the rearrangement of the electrons of a double bond to form a single bond with another molecule. The kinetic treatment of condensation polymerization focuses on the stepâgrowth mechanism, with a separate section devoted to cases of living polycondensation.
