Chemical Property of polyvinylacetate phthalate polymer
Edit
Chemical Property:
- Vapor Pressure:2.14E-06mmHg at 25°C
- Boiling Point:378.3°C at 760 mmHg
- Flash Point:196.7°C
- PSA：100.90000
- LogP:1.77600
- Solubility.: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.
