Summary: Poly(vinyl alcohol) (PVA) was derivatized by polymer analogous reaction with thienyl acryloyl chloride and processed to submicrometer fibers by electrospinning from aqueous solution. Water solubility of otherwise water‐soluble PVA fibers was reduced considerably by UV crosslinking of thienyl acrylate modified PVA fibers in the solid state. Water stability of these crosslinked fibers was proven by water steam test at 95 °C. UV/Vis spectrum of PVA‐Thio fibers irradiated for different periods at 300 nm. magnified image UV/Vis spectrum of PVA‐Thio fibers irradiated for different periods at 300 nm.
