General description

Poly(vinyl alcohol) (PVA) is a vinyl based water soluble polymer that can be used as a non-ionic surface active agent. It can also be used as a biodegradable polymer and can be incorporated in adhesives, coatings, textiles ceramics and cosmetics. Its properties include good transparency, chemical resistance, toughness and anti-electrostatic properties.


PVA can be used in the preparation of microspheres which can be further used as biodegradable microcarriers.
