Does anyone have an idea how to cause the PVA to precipitate from the solution ? may UV cause it to finish the polymerization process that will make it solid ?
thanks !!

I think that the gas will be thrown out from the water as it becomes Ice. If the freezing takes place in a closed vessel- the pressure inside it will increase. I don't think a substantial amount...
