POLYVINYL ALCOHOL (PVA)

Emulsion polymerization of styrene (St) and vinyl acetate (VAc) in the presence of conventional polyvinyl alcohol (PVA), PVA modified with a terminal alkyl group or PVA modified with a terminal thiol group (HS‐PVA) was compared. Whereas stable PVAc latexes were obtained, a stable PSt latex was obtained only in the case of HS‐PVA.

Polyvinyl acetate and polyvinyl alcohol. Polyvinyl acetate (PVA) and polyvinyl alcohol (PVOH) are further examples of ethylene copolymers. PVA is used as an emulsion adhesive for bag, sack and carton making. PVOH is produced by hydrolysis of PVA and the strong hydrogen bonding imparted by the –OH groups means that pure PVOH is water soluble.

Polyvinyl acetate (PVA or PVAc) is a thermoplastic polymer with a chemical formula of (C4H6O2)n. It is normally manufactured by the free radical polymerization of vinyl acetate.The procedure 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.

Pva in emulsion | Painters Pit Stop

I've decided to take a break from my usual recipes and pouring mediums and just go back to basics with PVA glue. I've not used it very often at all so I'll be interested to see how it works out. I'm using for this painting: PVA glue as a pouring medium at about 20-30% of the paint volume;

The tensile shear strengths of the emulsions were evaluated according to EN 204 and WATT 91. It was possible to fully, or partially, replace PVA as protective colloid with renewable materials. It was also possible to use renewable materials as additives or fillers in the emulsions. The emulsions obtained properties that differed from the reference.
