- Polyvinyl acetate
is a thermoplastic polymer with a
chemical formula of (C4H6O2)n -
Poly(vinyl acetate) may
be polymerized by bulk, solution, suspension, or emulsion techniques.
Commercially, emulsion polymerization is the predominant method.
-
Vinyl acetate is one of
the most important organic chemical raw materials. It is mainly used to
synthesize polyvinyl acetate, which is then turned into polyvinyl
alcohol (PVOH) by alcoholysis
-
Polyvinyl acetate (PVAc)
is basically manufactured in water dispersible form
-
The process involves the
reaction of monomer molecules of vinyl acetate by submerging them into
water. This results in the formation of a polyvinyl acetate emulsion
that is milky white in color. The emulsion fluid can then instantly be
processed as a polyvinyl acetate polymer in products comprising the PVAc
as a constituent element.
-
When PVAc is incorporated
into emulsion coatings and adhesives, it is normally converted to
polyvinyl alcohol first, which is a water-soluble polymer. This is done
by means of partial hydrolysis. On a lesser level, it is also used as a
protective coating for cheese to render it safe from humidity and fungi.
-
The degree of
polymerization of polyvinyl acetate typically is 100 to 5000. The ester
groups of the polyvinyl acetate are sensitive for alkali and will slowly
convert PVAc into polyvinyl alcohol and acetic acid.
-
Main uses are in
paints, adhesives, paper coatings and textiles
- In the CIS, only
four countries are turning out PVA dispersion: Russia, Ukraine, Belarus,
and Kazakhstan. The overall capacity for manufacturing this product
makes up 77,400 tons/year
