Crosslink PVA Physically: UV or Sensitizer?

[Marwa]

If we need to make a crosslinking for PVA using physical means, can we do this using uv without adding any agent or do we need to add something like a sensitizer ?!

PVA=polyvinylacetate?

No,polyvinyl alcohol. I know pva films dissolves in water, but i want to make a film with it that doesn't dissolve in water by using uv is that possible without adding any agent or not ?!

I would rather ask in the chemistry forum.
