MCQ
Correct statement for thermoplastic polymer is
  • A
    it does not become soft on heating under pressure
  • B
    it cannot be remoulded
  • ✓
    it is either linear or branched chain polymer
  • D
    it is cross-linked polymer.
✓

Answer

Correct option: C.
it is either linear or branched chain polymer
(c): Thermoplastics are the polymers in which intermolecular forces of attraction are neither very strong nor very weak and there are no cross-links between the chains. These can be casily moulded by heating i.e., it gets soft on heating and becomes hard on cooling. It is either linear or branched chain polymer.
