Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer used in manufacturing synthetic fabrics. It is also used as a suspension polymerization agent, as a base material in a variety of medical device applications due to its biocompatibility, and as a base polymer for additive manufacturing (e.g., 3D printing). Learn how FT-NIR spectroscopy offers a fast and non-destructive technique to determine transesterification degree during polyvinyl alcohol synthesis.
