    摘要: Substantially gel-free neutralised sulfonated elastomeric polymers having both good physical and rheological properties are made by a process wherein a sulfonated elastomer having 10 to 50 meq. of sulfonate groups per 100 gm polymer dissolved in a non-reactive solvent is neutralised with excess zinc acetate dissolved in methanol or methanol and water. the volume % of methanol based on non-reactive solvent being from 2 to 10, to form a zinc neutralised sulfonated polymer.
