Vinyl acetate ethylene reactions and solubility
Vinyl acetate ethylene reactions and solubility
(OP)
Hi
I am no chemical engineer in fact i am a geotechnical one but for the sake of my PhD i need your help. Idk if my question is well placed here but i wanna know what is the solubility of liquid VAE ( vinyl acetate ethylene ) in water before it hardens and does it ever react with sulfates like CaSo4 or NaSo4 as well as NaCl ? if so under which temperature ?

I don't know about the reactions you asked about.

To a ChE, the glass is always full - 1/2 air and 1/2 water.

I am looking forward into using VAE as a binder in soils, this technique has been used very recently where VAE is dilluted in water at ratios of VAE/Water of 1/10 and 1/20. if these soils contain appreciable amounts of sulfates or chlorides what are the possible reactions that may happen ?
RE: Vinyl acetate ethylene reactions and solubility
The solubility of a VAE polymer in water is essentially 0 g/l.
But, you can make a stable VAE latex (VAE polymer, water, and surfactant) that is 50-70 weight % polymer, 49-29 % water and 1 % surfactant). I bet you are thinking of a latex.

Latex
Emulsion
A VAE latex is made by polymerizing an emulsion of vinyl acetate, water, and surfactant, i.e. emulsion polymerization.

RE: Vinyl acetate ethylene reactions and solubility
why not use the polymer under powder form rather than liquid emulsion

@georgeverghese thanks alot it seems that sulfates are a building block for VAE latex , they also mention that sodium ions can help increase mechanical stability of this VAE dispersion , can you guys clarify what is mechanical stability ?
RE: Vinyl acetate ethylene reactions and solubility
Mechanical stability is the ability to flow or shear the VAE latex and it remain in it's original form. No coagulation. No formation of filterable solids. Etc. It is "stable".
