Instead, the parts of a given chain that are in the crystalline segments appear to be connected at the ends of the crystallites by random loops of disordered \(\ce{CH_2}\) sequences, something like an old-fashioned telephone switchboard. Buna-S or Buna-N is an example of copolymer. HARD. 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.). Their physical properties are particularly important in determining their usefulness, be it as rubber tires, sidings for buildings, or solid rocket fuels. These cross-links reduce plastic flow and provide a reference framework for the stretched polymer to return to when it is allowed to relax. 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.

Increasing order of their inter-molecular forces in the following compounds are as follows. The intermolecular forces for polymers are the same as for small molecules. Sulfonamides can be used as nylon flow aids and to retard degradation. A good elastomer should not undergo plastic flow in either the stretched or relaxed state, and when stretched should have a "memory" of its relaxed state. The results suggested that Nylon 66/Nylon 48 blends are miscible in all blend fractions. 1. Hydrogen has a lower electronegativity than chlorine, and so when chlorine bonds with hydrogen, a dipole is formed. This forces create a intermolecular bond called “hydrogen bond”. The approximate temperature below which glasslike behavior is apparent is called the glass temperature and is symbolized by \(T_g\). 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). The practical utility of polymers depends upon their mechanical properties such as, tensile strength, elasticity, toughness, etc. Fibers are solids having thread like structure possessing strong intermolecular force. The intermolecular forces present in polymers are van der waal’s forces and hydrogen bonding. 15.6 Arrange the following polymers in increasing order of their intermolecular forces. Polymers that are not highly cross-linked have properties that depend greatly on the forces that act between the chains. 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. The forces between the chains in the crystallites of polyethene are the so-called van der Waals or dispersion forces, which are the same forces acting between hydrocarbon molecules in the liquid and solid states, and, to a lesser extent, in the vapor state. Typical uses of these polymers. Intermolecular forces are generally much weaker than covalent bonds. Have questions or comments?
