See category for PI, PAM and their salts.

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

weight%       autoflammability (degrees C)

PI              0        410

PDPI       46.5       470

PPI          63.5       490      

PAM       100       calculated

r2=0.999

autoflammability = 1.27*weight%+410

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
