실험 절차

32.5 grams of a formulated Sulfo-EPT composition, 17.5 grams of HDPE, and 8.1 grams of stearic acid were blended in a Brabender mixing head for 13 minutes at 160° C. and 50 rpm. This blend was placed in a rubber mill and 2.6 grams of zinc acetate were added over a one minute time period while milling at 160° C. After the zinc acetate was completely added, the total blend was milled for an additional 31/2 minutes at 160° C. The Sulfo-EPT composition used in this experiment contained 30 milliequivalents of acid groups, and had been neutralized with 3 equivalents of magnesium hydroxide prior to blending. The amount of zinc acetate and stearic acid was sufficient to yield 3 equivalents of the preferential plasticizer zinc stearate.
