Dacron and Novolac are condensation polymers. This is almost everything that students need to know about addition and condensation polymers. Some examples of common condensation polymers are polyacetals, proteins, and polyamides. A small molecule such as water or hydrochloric acid is eliminated in each condensation. A small molecule such as water or hydrochloric acid is eliminated in each condensation. It is used for making good insulators, sheets, rods, switches, lacquers and adherent paints. Question 1. What is polymerisation? For example, polythene is formed by addition polymerization of ethene. One example of a condensation polymer is Nylon 6,6. [NCERT Exemplar] (a) Dacron (b) Buna-S (c) Neoprene (d) Novolac. The main difference between addition and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers with no by-products whereas in condensation polymerization, the polymers are formed due to the condensation more than one different monomers resulting in the formation of small molecules such as HCl, water, ammonia, etc., … Condensation Polymerisation- Process of formation of polymers by repeated condensation reaction between two different monomers, having bi-functionality or tri-functionality. Monomers are the. (ii) Condensation polymers: The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri … Some examples are polythene, nylon-66, bakelite, rubber, etc. Multiple Choice Questions . 11. Among them, starch and cellulose are the polymers of glucose molecules. Condensation polymers: ... Below is an example of the formation of Nylon 66, a common polymeric clothing material, involving one each of two monomers, hexamethylenediamine, and adipic acid, reacting to form a dimer of Nylon 66. Condensation Polymer:-The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. Rubber, polythene and nylon 6, 6 are examples of polymers. What is a homo-polymer? For example, nylon 6, 6 is formed by condensation polymerization of hexamethylenediamine and adipic acid. High degree polymerisation leads to rigid, hard, scratch resistant, infusible, attacked by alkalies phenolic resins. Write some examples of condensation polymers. For example, nylon 6, 6 is formed by condensation polymerization of hexamethylenediamine and adipic acid. BeTrained.in has solved each questions of NCERT Exemplar very thoroughly to help the students in solving any question from the book with a team of well experianced subject matter experts. Draw the repeating unit for a condensation polymer. Solution: Polymers are high molecular mass macromolecules, which are formed by repeating structural units derived from monomers. Some common examples of condensation polymers are:Formaldehyde resins These include polymers like Bakelite and Melamine polymers. NCERT Exemplar Class 12 Chemistry Chapter 15 Polymers. big size molecules, they are also called macromolecules Monomers: The simple molecules which combine to form polymers by forming single or multiple bonds are […] Some examples are ethene, vinyl chloride, acrylonitrile, phenol and formaldehyde etc. • Each monomer has two of the same functional groups. Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. Describe what is meant by a condensation polymer. Ans. A small molecule such as water or hydrochloric acid is eliminated in each condensation. Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. We have provided Polymers Class 12 Chemistry MCQs Questions with Answers to help students understand the concept very well. CBSE Class 12. fibres (nylon 6,6) and synthetic rubbers (Buna - S) are examples of man-made polymers extensively used in daily life as well as in industry. Example: polythene. (i) Phenol formaldehyde resins (Bakelite): Q2: Explain natural and synthetic polymers with the help of two examples of each type? A small molecule such as water or hydrochloric acid is eliminated in each condensation.
