Step-by-step solution
(A) Glyptal polymer is used as a manufacture of paints and Lacquers (B) Neoprene is formed by the free radical polymerisation of chloroprene. It is used for manufacturing conveyor belts, gaskets and hoses. (C) Polyacrylonitrile is used as a substitute for wool in making commercial fibres as orlon or acrilan. (D) Low density polythene (LDP) is chemically inert and tough but flexible and a poor conductor of electricity. Hence, it is used in the insulation of electricity carrying wires and manufacture of squeeze bottl
