Among the following, the correct statement(s) about polymers is(are)
Multiple Choice Options
- A The polymerization of chloroprene gives natural rubber.
- B Teflon is prepared from tetrafluoroethene by heating it with persulphate catalyst at high pressures.
- C PVC are thermoplastic polymers.
- D Ethene at 350-570 K temperature and 1000-2000 atm pressure in the presence of a peroxide initiator yields high density polythene.
Step-by-Step Verified Solution
(A) Polymerization of chloroprene gives synthetic rubber.
(B) Teflon is manufactured by heating tetrafluoroethene with a free radical or persulphate catalyst at hight pressure.
(C) Polyvinyl chloride (PVC) is a thermoplastic polymer and used in making hand bags, vinyl flooring and water pipes.
(D) Ethene at 350-570 K temperature and 1000-2000 atm pressure in the presence of a peroxide initiator yields low density polythene.
