Question

High-density polythene (HDPE) is synthesized at significantly lower pressures than LDPE. According to standard manufacturing processes, what is the upper limit of the typical pressure range (in atm) used for HDPE synthesis with a Ziegler-Natta catalyst?

Prashant Kotian · Accepted Answer

Correct answer: 7. The polymerization of ethene to HDPE using a Ziegler-Natta catalyst takes place under a relatively low pressure of atmospheres. Thus, the upper limit of this specific range is 7.
