Description
The effects of residual acetyl group rates of poly (vinyl alcohol) s (PVA) on the stability of pyrithion zinc particle (Zpt) dispersion were examined. With decrease in the residual acetyl group rate of PVA, Zpt dispersion became less stable in sodium dodecyl sulfate (SDS) solution. However, in NaCl solution, the residual acetyl group rate of PVA had no effect on Zpt stability.<BR>The amount of SDS adsorbed on PVA and that of PVA on Zpt were determined. When the residual acetyl group rate of PVA decreased, the amount of SDS adsorbed on PVA was noted to decrease and that of PVA on Zpt to increase.<BR>The PVA-SDS complex was prepared for use as a dispersing agent. The stability of Zpt dispersed by this complex in NaCl solution was studied and found to depend on the quantity of the PVA-SDS complex present. These results indicate that PVA may be concluded to form complexes with SDS at acetyl groups by which Zpt dispersion is stabilized.
