Superabsorbent polymers comprising direct covalent bonds between polymer chain segments and method of making them

Patented is a superabsorbent polymer particle comprising polymer chain segments. The superabsorbent polymer particle having a surface that includes a plurality of evenly distributed, homogeneous surface crosslinks and a core, that includes crosslinks, wherein said surface crosslinks are direct covalent bonds formed directly between aliphatic carbon atoms of said polymer chain segments on said surface;  wherein said crosslinks in the core are substantially free of direct covalent bonds formed directly between aliphatic carbon atoms of said polymer chain segments in said core.
