What Is Polyvinyl Alcohol? Polyvinyl alcohol, aka PVA, PVOH or E1203, is a synthetic plastic polymer. In our homes, it’s most commonly found as the thin wrapping around dishwasher and laundry pods.

However, these means have limited efficacy and require many processing steps. In contrast, the PVA copolymer's strong oxygen-blocking ability is expected to protect against oxidation with a simple ...

Structure studies were performed on PVA gels in mixtures of dimethyl sulfoxide (DMSO) and water using various scattering methods to see the hierarchic structure. It was found that the crosslinking ...
