물성
물리화학적 성질
- 용해도
- -2 · 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.

Polyvinyl acetate phthalate is a free-flowing white to off-white powder and may have a slight odor of acetic acid. The material is essentially amorphous.
화학 및 산업
제조 방법
생산 방법Polyvinyl acetate phthalate is a reaction product of phthalic anhydride, sodium acetate, and a partially hydrolyzed polyvinyl alcohol. The polyvinyl alcohol is a low molecular weight grade, and 87–89 mole percent is hydrolyzed. Therefore, the polyvinyl acetate phthalate polymer is a partial esterification of a partially hydrolyzed polyvinyl acetate.
