See category for PI, PAM and their salts.

The density was calculated by using linear regression of the measured densities for PI, PDPI and PPI (y-values) versus the weight percentage of PAM (x-values) in each of the substances:

weight%       density (g/cm3)

PI              0        1.15

PDPI       46.5       1.38

PPI          63.5       1.54       

PAM       100       calculated

r2=0.97

density=0.0059*weight%+1.14

PI = 2-phenyl-2 -imidazoline, CAS 936-49 -2

PAM = benzene-1,2,4,5 -tetracarboxylic acid, CAS 89 -05 -4

PDPI = 1 mol PAM plus 2 mol PI, CAS 54553 -91 -2

PPI = 1 mol PAM plus 1 mol PI, CAS 54553 -90 -1
