polyvinyl acetaldehyde Usage And Synthesis
  • Industrial usesThese are relatively soft, water-insoluble thermoplasticproducts obtained by the reaction ofpolyvinyl alcohol with aldehydes. Propertiesdepend on the extent to which alcohol groupsare reacted. Polyvinyl butyral is rubber andtough and is used primarily in plasticized formas the inner layer and binder for safety glass.Polyvinyl formal is the hardest of the group. Itis used mainly in adhesive, primer, and wirecoatingformulations, especially when blendedwith a phenolic resin.
    Polyvinyl butyral is usually obtained by thereaction of butyraldehyde with polyvinyl alcohol.The formal can be produced by the sameprocess, but is more conveniently obtained bythe reaction of formaldehyde with polyvinylacetate in acetic acid solution.
