Q18 / 180 · KCET 2018 · Chemistry

ziegler - Natta catalyst is used to prepare

  • A
    Low - density polythene
  • B
    Teflon
  • Correct answer
    C
    High - density polythene
  • D
    Nylon-6

Solution

Zeigler-Natta Catalyst is \( \mathrm{TiCl}_{4} \) and \( \mathrm{Al}\left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{3} \) minium and titanium tetrachloride) and it is used to prepare high
density polythene (HDP) by addition polymerization at a temperature of \( 333 \mathrm{~K} \) to \( 334 \mathrm{~K} \) under pressure condition of \( 6-7 \)
atm.

Hence, the correct answer is option: 'C'.
