The Anthranilate Amide of 'Polyethylene Carboxylic Acid' Shows and Exceptionally Large Change with pH in Its Wettability by Water

Abstract

The amide formed from polyethylene carboxylic acid (PE-CO2H) and anthranilic acid shows an exceptionally large change in wettability by water with pH. The values of advancing contact angles theta(a) are theta(a)(pH 1) = 110 degs and theta(a)(pH 12) = 33 degs. Comparison of these values with those for corresponding amides of meta- and para-aminobenzoic acid and aniline suggest that both conformational mobility of the polar functional group at the solid- water interface and surface roughness contribute to this large value.
