Which of the following polymers have vinylic monomer units?

(A) Acrilan

(B) Polystyrene

(C) Nylon

(D) Teflon

This is a multiple choice answer as classified in NCERT Exemplar

Option (A), (B) and (D)

Explanation: Polyacrylonitrile is formed by the addition polymerisation of acrylonitrile in the presence of a peroxide catalyst. Polyacrylonitrile is used as a wool substitute in the manufacture of commercial fibers such as orlon or acrilan.

Polystyrene has the monomer unit styrene.

Teflon is made by heating tetrafluoroethene at high pressures with a free radical or persulphate catalyst.
