Melt the A-C Polyethylene 629 and the emulsifier together at 257'f maximum. When completely melted, cool to 230'F. With the temperature of the melt at 230'F, slowly add the Potassium Hydroxide solution with stirring to break up the foam which forms. Care should be exercised in this operation. If the temperature is too high or the solutionn is added too rapidly, the material will foam over the top of the heating kettle. While the A-C Polyethylene 629 is being melted, heat the water (bring to a boil and turn off heat just before using). With rapid stirring (but below speed at which air is whipped in), slowly add the melt to the water. During the addition, the temperature of the melt should be maintained at 230'f and the water maintained at 203-210'F (not boiling). Add the melt at a steady rate to the top of the vortex formed by the stirring action (the melt stream should not hit the side of the vessel or the stirrer shaft). With proper addition, the melt will spiral down the vortex and be emulsified.
