Solution

Part (i):

Bakelite, a network polymer, is used for making combs, phonograph records, electrical switches and handles of various utensils.

(i) Bakelite (d) Tyre,cords

Part (ii):

Low-density polythene (LDPE) is tough but not hard and hence used in the manufacture of squeeze bottles, toys and flexible pipes.

(ii) Low-density polythene (e) Non-stick cookware

Part (iii):

Melamine-formaldehyde resin is used in the manufacture of unbreakable crockery

(iii) Melamine formaldehyde resin (a) Electrical switches

Part (iv):

Nylon 6, a polyamide polymer of caprolactam, is used to manufacture tyre cords, fabrics and ropes.

(iv) Nylon-6 (f) Packaging material for shock absorbance

Part (v):

Polytetrafluorethylene or Teflon is used in making oil seals and gaskets. It is also used in non-stick surface coated utensils.

(v)
Polytetrafluoroethene
(b) Non-stick Cookware

Part (vi):

Polystyrene is used as an insulator and as a wrapping material. It is also used in the manufacture of toys, radio and television cabinets

(vi) Polystryene (c) Unbreakable crockery
