Sodium detaches itself,
leaving only carboxyl ions.
Being negatively charged,
these ions repel one another.
The polymer unwinds and absorbs water,
which is attracted by the sodium atoms.

Grafting onto
“Grafting-onto” involves the chemical reaction preformed, functionalized polymers with surfaces containing complementary functional groups
Grafting from
‘‘Grafting-from’’ involves an in situ polymerization of an initiator functionalized surface with monomer.
