Vedclass · Answer

(A) $HDPE$ is prepared by coordination polymerization using the Ziegler-Natta catalyst (a mixture of triethylaluminium and titanium tetrachloride).This process occurs through the formation of coordination complexes.Ethylene molecules coordinate with the transition metal catalyst,leading to linear chain growth.The resulting polymer has a high density $(0.97 \ g/cm^3)$ and a higher melting point $(403 \ K)$ compared to $LDPE$ (density $0.92 \ g/cm^3$ and melting point $384 \ K$).

High density polyethylene $(HDPE)$ can be prepared from ethylene by
