Fibre polymers are the thread forming solids which possess high tensile strength and have high modulus. An example is nylon-6,6.
A) Rubber is an elastomer.An elastomer is a polymer with viscoelasticity and very weak intermolecular forces, generally having low Young's modulus and high failure strain compared to other materials.
B) Nylon-6,6 is a fibre formed by condensation polymerisation of hexamethylenediamine with adipic acid under high pressure and temperature (as shown in figure above).Fibre polymers are the thread forming solids which possess high tensile strength and have high modulus.
C) PVC (Polyvinyl chloride) is a thermoplastic polymer.Thermoplastic polymer is a polymer that becomes pliable or moldable above a specific temperature and solidifies upon cooling.
D) Bakelite is an example of thermosetting polymer.
Thermosetting polymers are the polymers which are liquid or malleable at low temperatures but which change reversibly to become hard at higher temperatures.
