Standard Test Method for Acid Number (Empirical) of Maleic Anhydride (MAH) Grafted Waxes

Importancia y uso:

4.1 This test method is used to determine the free acid content of MAH-grafted waxes. The potential hydrolysis of the anhydride functionality of this wax in storage makes them unsuitable for determining free acid content by Test Method D1386. Free acid content is a significant quality control test, and is a determinant of the utility of the wax.
