Question

From the following list, how many polymers are classified as Thermoplastic polymers based on their intermolecular forces? Polythene, Polystyrene, Polyvinyl chloride (PVC), Bakelite, Nylon-6,6, Urea-formaldehyde resin, Teflon.

Prashant Kotian · Accepted Answer

Correct answer: 4. Thermoplastics are linear/slightly branched polymers that soften reversibly on heating. Polythene, Polystyrene, Polyvinyl chloride (PVC), and Teflon are thermoplastics. Bakelite and Urea-formaldehyde are thermosetting. Nylon-6,6 is a fibre. Thus, the count is 4.
