A sample of high-density polyethylene (HDPE) has a molecular weight of u. What is the approximate de — Polymers Chemistry Question

💡 Solution & Explanation

The degree of polymerization is the total mass divided by the mass of the repeating unit. The monomer of polyethylene is ethene ($C_2H_4$), which has a molecular mass of $28$ u ($12 \times 2 + 1 \times 4$). $DP = 280000 / 28 = 10000$.
