Vinyl polymers that do not dissolve in water after film formatio?
Answers
Polyvinyl formal (PVF) and Polyvinyl acetate (PVAc) are the vinyl polymers that are highly insoluble in water instead they form a film in water instead they dissolved in anionic surface-active agent resolution.
compound solutions of PVF, PVAc, and polyvinyl alcohol in surface-active agent were studied viscometrically and electrophoretically. The compound forms a posh with the surface-active agent, the behaviour of that is analogous to it of electrolyte. The advanced is charged and migrates to the anode. With qualitative analysis of the answer of polymer‐surfactant advanced against running water, the compound separates out; but, the compound doesn't separate of undialyzed resolution, notwithstanding the answer is diluted to way less concentration than the CMC of the surface-active agent. therefore the dissolution of the compounds within the surface-active agent resolution is because of the homeward adsorption of surface-active agent ions on the polymer molecule. the quantity of adsorb-able surface-active agent ions was calculable. The adsorption could be of the Langmuir sort.
