Degradability of other polyesters There are two main water-soluble polymer types commercially available polyvinyl alcohol (PVOH) and ethylene vinyl alcohol (EVOH). PVOH is a readily biodegradable, water-soluble polymer. The degradation of PVOH is influenced by its crystallinity and molecular weight PVOH does not biodegrade, but simply dissolves in water or can be biodegraded by activated sludge treatment. EVOH is another water-soluble synthetic plastic. [Pg.62]
