   Among the following, the correct statement(s) about polymers is(are)
   1. A.The polymerization of chloroprene gives natural rubber.
   2. B.Teflon is prepared from tetrafluoroethene by heating it with persulphate catalyst at high pressures.
   3. C.PVC are thermoplastic polymers.
   4. D.Ethene at $350-570K$ temperature and $1000-2000$ atm pressure in the presence of a peroxide initiator yields high density polythene.
   Show answer & solution

   Answer: B,C

   (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 $350-570K$ temperature and $1000-2000atm$ pressure in the presence of a peroxide initiator yields low density polythene.
