Nylon-66 is formed by condensation between hexamethylene diamine and adipic acid as shown below: Classification of polymers based on molecular force. Correct answer - "c" Step by step explanation: The polymers can be divided on the basis of molecular powers such as vander waal forces, hydrogen bonding and dipole interactions. The effect of temperature on the physical properties of polymers is very important to their practical uses. Arrange the following polymers in increasing order of their intermolecular forces. Because the acid is acidic and the amine is basic, they first react together to form a salt. Check Answer and Solution for above question from Ch. 4. Fibers are solids having thread like structure possessing strong intermolecular force. ⇒ Dacron is a condensation polymerisation product of hexamethylene diamine and adipic acid. Typical uses of these polymers. Increasing order of their inter-molecular forces in the following compounds are as follows. This property of nylon allows fabrics to be made with higher resistance to intense forces. Before the name Nylon 6,6 was used , it was called by a codename “fiber 66” Nylon 6. These crystalline regions are called crystallites (Figure 29-3). For example, it requires 927 kJ to overcome the intramolecular forces and break both O–H bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100°C. Another temperature of great importance in the practical use of polymers is the temperature at which thermal breakdown of the polymer chains occurs. Being more crystalline, rate of dyeing of nylon 66 is relatively slower with reasonably better fastness of dyeings. Nylon 66 is often selected for use because of its combination of toughness, stiffness, high melting point and chemical resistance. DNA forms because of hydrogen Proteins form their secondary and tertiary structures through hydrogen-bonding and London forces. These forces are intermediate of the forces present in the elastomers and in the fibres. Name all intermolecular forces that attract polymer chains in nylon-6,10. (1) Elastomers (2) Thermoplacstics (4)Thermosetting. The practical utility of polymers depends upon their mechanical properties such as, tensile strength, elasticity, toughness, etc. These forces are relatively weak and arise through synchronization of the motions of the electrons in the separate atoms as they approach one another. Sulfonamides can be used as nylon flow aids and to retard degradation. These cross-links reduce plastic flow and provide a reference framework for the stretched polymer to return to when it is allowed to relax. A cube of side 4 cm contains a sphere touching its sides. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. The monomer units of nylon-66 are obtained by the reaction of hexamethylene diamine and adipic acid. Their physical properties are particularly important in determining their usefulness, be it as rubber tires, sidings for buildings, or solid rocket fuels. 4] Classification Based on Molecular Forces Intramolecular forces are the forces that hold atoms together within a molecule . Nylons are widely used because they have a good cost to performance ratio. Match Column-I with Column-II. Statement 2: Intermolecular forces of attraction in terylene are H-bonding. A sphere and a right circular cylinder of the same radius have equal volumes. Correct answer - "c" Step by step explanation: The polymers can be divided on the basis of molecular powers such as vander waal forces, hydrogen bonding and dipole interactions. Share with your friends. Typical modifiers are flame retardents to reduce As we know that elastomers (Buna-S) have weak intermolecular forces, fibres (Nylon-6, 6) have dipole-dipole interaction, thermoplastics (Polythene) have intermolecular forces intermediate between elastomers and fibres and thermosetting polymers (Bakelite) undergoes permanent change on heating. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Because polymer molecules are so large, though, the magnitude of their intermolecular forces can vastly exceed those between small molecules. Increasing order of their inter-molecular forces in the following compounds are as follows. Teflon. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Because of the strong forces, the chains are closely packed, giving them high tensile strength and less elasticity. Share 5. resistance to heat. This difficulty is overcome in making polypropenenitrile (Orlon) fibers by dissolving the polymer in $$\ce{N}$$,$$\ce{N}$$-dimethylmethanamide and forcing the solution through fine holes into a heated air space where the solvent evaporates. Buna-S or Buna-N is an example of copolymer. Thus when a sample of the crystalline polymer is stressed to the point at which it fractures, carbon-carbon bonds are broken and radicals that can be detected by esr spectroscopy (Section 27-9) are generated. -200+ Video lectures 15.6 Arrange the following polymers in increasing order of their intermolecular forces. 1) Nylon-66 , 2) Polyisoprene, 3) Bakelite, 4) Polystyrene, 5) NULL [Hint : Strong intermolecular forces of attraction like Hydrogen bonding.

Legal. 3. Join now. For example: Nylon 66, Dacron, etc. Intermolecular forces are generally much weaker than covalent bonds. Answer: (i) FIBRES:-T he polymers in which long chains are held together by strong intermolecular forces are called fibres.E.g. 1) Nylon-66 , 2) Polyisoprene, 3) Bakelite, 4) Polystyrene, 5) NULL The intermoleculer forces in ther-mosplastic polymers are intermediate to that of elastomers & fibres. Because of its light weight, incredible strength, durability and high damage resistance, it has somehow replaced the use of silk, especially in making fabrics. Lower numbered nylons, 6 ,6-6, 4-6, absorb moisture and change their properties as a result. more abrasion resistant. This results in close packing of chains and thus impart crystalline nature to the fibres.] Figure 29-6: Schematic representation of an oriented crystalline polymer produced by drawing the polymer in the horizontal direction. Nylon-6, 6 is a fibre, it contains intermolecular hydrogen bonding. Physical properties such as tensile strength, x-ray diffraction pattern, resistance to plastic flow, softening point, and elasticity of most polymers can be understood in a general way in terms of crystallites, amorphous regions, the degree of flexibility of the chains, cross-links, and the strength of the forces acting between the chains (dispersion forces, hydrogen bonding, etc.). This allows nylon to be re-melted and pelleted for re-use. -Chapter-wise tests. Post Answer. having higher melting point. Find : the total surface area. Statement 1: Nylon fibres are stronger than terylene fibres. Depending on the orientation of adjacent polymer chains, intermolecular forces between nylon-6,10 chains might be stronger or weaker. Too much sulfur completely destroys the elastic properties and produces hard rubber of the kind used in cases for storage batteries. The chemistry of the vulcanization of rubber is complex. These forces are either hydrogen bonds or dipole-dipole interactions. The Nylon 66/Clay in this study has a nonlinear elastic behaviour. The attractive force that results is rapidly overcome by repulsive forces when the atoms get very close to one another (see Figure 12-9, which shows how the potential energy between a pair of atoms varies with the internuclear distance).
