性质

溶解度 Polycarbophil polymers do not dissolve in water but
can swell in water to around 1000 times their original volume (and ten times their original diameter) to form gels when exposed
to a pH environment above 4–6. Since the pKa of these polymers
is 6.0±0.5, the carboxylate groups on the polymer backbone
ionize, resulting in electrostatic repulsion between the negative
particles, which extends the molecule, adding to the swelling of
the polymer.
