Is water is a polymer ?

What is the physical property of polymer

• As chain length and cross-linking increases, the tensile strength of the polymer increases.

• Dipole-dipole bonding side chains enable the polymer for high flexibility

• Polymers with Van der Waals forces linking chains are known to be weak, but give the polymer a low melting point.
