  • Coating composition containing a low MFI ethylene acrylic acid copolymer
    Patent number: 6852792
    Abstract: This invention is directed to the discovery that ethylene-acid copolymers that have low melt flow index MFI (namely less than 100 g/10 min measured according to ASTM D1238 at 190° C., 2.16 kg) even with low acid content (such as less than 20 wt. %) can provide stable aqueous dispersions directly in aqueous media (i.e. free from any other solvent) with less than 1 wt. % non-dispersibles in single bases even at mild dispersion process conditions, at temperature less than 100°C., atmospheric pressure, and with low agitation speed.
