The polymer having strongest intermolecular forces is

The polymer having strongest intermolecular forces is Correct Answer Nylon-6

Concept:

POLYMERS

  • Polymers are large molecules that are made up of hundreds of monomers that are joined together in order to form long chains. 
  • Polymers are held together by strong covalent bonds. Since they are very long molecules so that the intermolecular forces are relatively strong. 
  • Monomers are the small molecules that are linked to the polymers. 

Explanation:

Classification of Polymers based on Molecular Forces.

Elastomers Fibres Thermoplastic Polymers Thermosetting Polymers
These polymers have elastic properties and are rubber-like solids that can return to their original shape when the force is removed. These polymers are long, thin thread-like solids having high tensile strength and high modulus.  These polymers are capable of repeatedly softening on heating and hardening on cooling.  These polymers are cross-linked or heavily branched molecules, which on heating undergo extensive cross-linking in moulds and again become infusible.
These have the weakest intermolecular forces between polymer chains that permit polymer to be stretched out. These have strong intermolecular forces such as H-bonding, dipole-dipole interactions. These polymers possess intermolecular forces of attraction and are intermediate between elastomers and fibres. These cannot be reused.
Buna-S, Buna-N and neoprene are examples of elastomers. Polyamides(nylon 6,6, nylon-6) and polyesters (terylene) are examples of fibres. Polythene and polystyrene are examples of thermoplastic polymers. Bakelite and urea-formaldehyde polymer are examples of thermosetting polymers. 

 

  • Nylon-6 is formed by the ring-opening polymerisation of caprolactam.

The intermolecular forces present between the Nylon-6 is hydrogen bond. Hence it comes under the category of fibres.

Melt spinning of polymers involves the forcing of polymer melt through spinnerettes (fine holes) into an atmosphere kept at a temperature lower than the melting point of the polymer, which causes the fine diameter polymer melt to harden into filaments. Melt spinning is not used in case of the __________ fibres.
