Question
Low-density polythene (LDPE) is obtained by the free-radical addition polymerization of ethene. Which of the following best describes the extreme reaction conditions required for its synthesis?
Answer: A
💡 Solution & Explanation
LDPE requires highly extreme conditions to force the ethene molecules together for free-radical polymerization: $1000 - 2000$ atm pressure and a temperature of $350 - 570$ K. It also requires a radical initiator like traces of oxygen or a peroxide.
