Sodium polyacrylate is a cross-linked (network) polymer that contains sodium atoms.
Sodium polyacrylate absorbs water by a process called osmosis.
When the (sodium-containing) polymer is placed in contact with water, there is a tendency for the sodium to distribute equally between the network and the water.
That means, some of the sodium atoms want to leave the network and move to the water.
When these sodium atoms leave, they are replaced with water molecules.
Water swells the polymer network to try to keep the sodium concentration balanced between the polymer and the water.
The cross-links that connect the chains together prevent them from dissolving/breaking apart in the water.

HOW 2-Propenoic acid, sodium salt IS MADE?
Sodium polyacrylate is produced by the reaction between acrylic acid (H2C=CHCOOH) and its sodium salt (H2C=CHCOONa).
The product of this reaction is a long-chain copolymer consisting of alternate units of acrylic acid and sodium acrylate.
Sodium polyacrylate is a polymer made of two different monomers, in this case, acrylic acid and sodium acrylate.
What makes Sodium polyacrylate different from most other kinds of polymers is that adjacent polymer chains are able to cross link with each other.
The hydrogen on a carboxyl group (-COOH) on one chain reacts with a double bond (-C=C-) on an adjacent chain, forming a link that holds the two chains together.
Cross-linking occurs at many points in Sodium polyacrylate, resulting in the formation of a mesh-like web consisting of polymer chains.
When water is added to Sodium polyacrylate, it forces carboxyl groups away from each other, forcing the mesh to open up and make space for water molecules to fill the gaps in the polymer.
As more water is added, the carboxyl groups stretch even farther apart, making room in turn for yet more water molecules to be absorbed by the polymer.
If Sodium polyacrylate is allowed to dry out, water molecules leave gaps in the compound, the empty spaces between carboxyl groups collapse, and Sodium polyacrylate returns to Sodium polyacrylates original size.
Sodium polyacrylate can then be stored and re-used any number of times.
