Poly(vinyl alcohol) (PVA) is a water soluble, semicrystalline polymer with many useful qualities such as high tensile strength and abrasion resistance. Dehydration during processing plays an important role in controlling the crystallisation and structure of PVA and so the dehydration process has attracted a lot of attention in recent years. In the latest Polymer International, Zhang et al unveil a simple model for dehydration rates of thermally processed PVA.
