Abstract: A self-emulsifiable resin powder can be dispersed in water without utilizing additional surfactants or expending large amounts of mechanical energy. Such self-emulsifiable resin powders offer numerous distinct advantages over conventional latices. One of the most important benefits that is realized by utilizing self-emulsifiable resin powders is that they can be shipped dry which is the equivalent to shipping a latex with a 100 percent solids content. In other words, such self-emulsifiable resin powders eliminate the necessity for shipping water in latices. The self-emulsifiable resin powders disclosed herein also have the advantage of having low carboxyl contents and of being dispersible into aqueous systems which contain virtually no surfactants. These self-emulsifiable resins contain a relatively small proportion of repeat units which are derived from both acrylic acid and methacrylic acid.
