High-density polyethylene (HDPE) It is obtained by coordination polymerization using Ziegler-Natta catalyst. It has a higher melting point $\left(130^{\circ }\mathrm{C}\right)$ and higher density $\left(0.97\mathrm{g}{\mathrm{cm}}^{-3}\right)$. It has a linear polymer chain and hence has greater strength and heat resistance.Polyethylene (low density, m. p. $110^{\circ }\mathrm{C}$
