Descripción general

Poly(vinyl acetate) (PVAc) is a non-crystalline, atactic polymer. It is prepared from vinylacetate monomer via free radical polymerization. It is commonly usedin the food industry due to its low toxicity and excellent flexibility. PVAc films are used as emission sensors forvehicles and in oral drug delivery products.

Aplicación

Poly(vinyl acetate) can be used as a:
  • Starting material to prepare polymer fibers for gas and humidity sensor applications. Citric acid-doped PVAc nanofibrous mats can be used to develop sensors for trimethylamine gas at room temperature.
  • Polymer coating for floating tablets showing a controlled drug delivery. PVAc is a suitable excipient to ensure reliable and safe drug release. PVAc-based matrix tablet flow due to intrinsic low density and high elasticity of polyvinyl acetate coating.
It can also be used to prepare cellulose nanofibrils(CNF)-PVAc nanocomposite adhesives by simple mixing of CNFs suspension with PVAc and polyvinyl alcohol solution. The addition of CNFs enhances the mechanical properties of the nanocomposite.
