Can multiple freeze-thaw cycles be performed on a hydrogel (PVA/PVP) for crosslinking without changing the mechanical properties?

The polymer goes through 6 freeze-thaw cycles (21 hours at -19C and 3 hours at 25C). Does anyone know, if I perform 2 or 3 cycles in a day, would the polymer be the same?
