| 溶解度 | Soluble in ethanol and methanol; sparingly soluble in
acetone and propan-2-ol; practically insoluble in chloroform,
dichloromethane, and water. In buffer solutions, polyvinyl
acetate phthalate (200 mg/L) is insoluble below pH 5 and
becomes soluble at pH values above 5. Polyvinyl acetate
pththalate shows a sharp solubility response with pH; this
occurs at pH 4.5–5.0, which is lower than for most other
polymers used for enteric coatings. Solubility is also influenced
by ionic strength. |
