L.D.P.E has a .......melting point than H.D.P.E​

Answer 1

L.D.P.E has a .......melting point than H.D.P.E​

LDPE has a lower melting point than HDPE.

Explanation:

LDPE is a tough and flexible polyethylene. It has higher degree of short and long side-chain branching. Branching makes the molecules to pack hard, stiff, crystalline domains resulting in lower density and crystallinity, flexibility and toughness. LDPE has a lower melting point than HDPE. HDPE crystals are larger and uniform than that of LDPE. HDPE is denser, rigid and less permeable than other types of polyethylene.
