The composition and structure of the base EPDM and the sulfonate content of the metal sulfonate-containing EPDM exert substantial effects on the mechanical and flow properties of ionomers. The systems discussed to this point have all contained zinc sulfonate groups. In terms of melt flow the zinc cation is the cation of choice. The metal cation borne by... [Pg.15]

The composition and structure of EPDM and the composition of the ionomer affect the mechanical and flow properties of the ionomer. Another parameter that affects ionomer properties is the concentration of metal acetate, specifically zinc acetate, present in the neutralized sul-fonated EPDM. This is illustrated in Figure 5, where the melt viscosity of zinc sulfonate CR-2504 is plotted as a function of zinc acetate concentration. Zinc acetate was added to a cement of the polymeric acid, and the resultant neutralized polymer was isolated through the solvent flashing of the cement. Essentially all of the zinc acetate that was added to the polymeric free acid was retained by the polymer (cf. Table II). [Pg.18]

The effect of zinc stearate concentration on the melt flow of zinc, magnesium, and barium sulfonate-containing CR-2504 is shown in Figure 4. These results parallel those obtained with stearic acid plasticizer (cf. Table I). The zinc sulfonate EPDM responded most readily to zinc stearate plasticization. Although the melt flows of the magnesium and... [Pg.47]

The plasticizing effects of a larger number of metal stearates on the zinc sulfonate ionomer were examined, and the results are given in Table III in terms of flow and mechanical properties. Lead stearate, zinc stearate, and ammonium stearate significantly improved melt flow along with the stearic acid control. The barium, magnesium, sodium, lithium, and calcium stearates showed little, if any, improvement in melt flow. Of the four melt flow improvers, both stearic acid and ammonium stearate exerted deleterious effects on tensile properties. Only the zinc and lead stearates substantially improved tensile properties. Thus, while zinc stearate is not unique, the number of fatty acid derivatives that improve both melt flow and mechanical properties is limited. [Pg.49]
