What range of temperature is generally employed for low density polyethylene formation on kinetic considerations?
Answer & explanation
Correct answer: option 2
The correct answer is option 2. 170-250 ᵒC.
The temperature range generally employed for the formation of low-density polyethylene (LDPE) is indeed 170-250 ᵒC.
The production of low-density polyethylene (LDPE) via free radical polymerization requires specific conditions. The process typically involves:
High Pressure: Around 1000-3000 atmospheres.
Temperature: The typical temperature range is indeed around 170-250 °C. This temperature range is suitable for generating free radicals necessary for the polymerization of ethylene.
The correct temperature range for the formation of LDPE on kinetic considerations is 170-250 °C. This range allows for efficient free radical polymerization under the required high-pressure conditions. Therefore, the correct answer is 170-250 ᵒC.
