Nothing.
The crystallization that occurs upon drying makes it inherently more difficult to resolvate.

Just for information, and I assume not used in childrens type glue, but aluminium chloride is added to PVA wood glues in some instances to improve water resistance - such as when making laminates for kitchen surfaces.

PVC becomes not soluble in hot water due to crosslinking during heat treatment.
