polyvinyl alcohol , PVA (Abkürzung)

The first synthetic absorbable was based on polyvinyl alcohol in 1931.

Polyvinyl Alcohol, however, is said to have negative effects on the final mold's surface finish.

It is prepared from polyvinyl alcohol by reaction with butyraldehyde.

Consumption of polyvinyl alcohol was over one million metric tons in 2006.

Polyvinyl alcohol should work as well as Methocel, but you may still have the same problem.

Polyvinyl alcohol is the raw material to make other polymers like:

The commercially most successful pervaporation membrane system to date is based on polyvinyl alcohol.

Polyvinyl alcohol has excellent film forming, emulsifying and adhesive properties.

With the polyvinyl alcohol acting as glue to hold the nanotubes together, they can be spun into a fiber and dried.

Sometimes organic binders such as polyvinyl alcohol are added to hold the green body together; these burn out during the firing (at 200-350 C).

The "slime" reaction involves sodium borate and polyvinyl alcohol.

You could also use a "thickener", e.g. polyvinyl alcohol, to adjust the viscosity.

Some other uses of polyvinyl alcohol include:

First, a protection and support bandage of cotton gauze and polyvinyl alcohol is applied.

This enzyme participates in bacterial polyvinyl alcohol degradation.

High tensile strength fibers-Fibers produced with polyvinyl alcohol required 600 J/g to break.

The North Korean-manufacture fiber Vinalon is produced from polyvinyl alcohol.

It is a thermoplastic substance with softening zone between 30-45 C, depending on the molecular weight of the starting polyvinyl alcohol.

It should not be confused with the related polymer polyvinyl alcohol, which is also called PVA.

As coating material, A. W. Trochimczuk et al. used polyvinyl alcohol.

Here, they used water-soluble polyvinyl alcohol (PVA) sheets in the same manner.

However it is quite possible that PVA (polyvinyl alcohol), the monomer in this reaction.

This often has a profound effect on polymer properties-fluorination of polyvinyl alcohol, for instance, improves its resistance to strong acids and bases.

Other names in common use include dehydrogenase, polyvinyl alcohol, and PVA oxidase.

I recently read the Elmer's glue contains 2 polymers - polyvinyl alcohol and polyvinyl acetate.
