<p>Two new hybrid compounds were synthesized by combining potassium N–(4-methylphenylsulfonyl)dithiocarbimate (DCBI) with layered zinc hydroxy salts: zinc hydroxynitrate (ZHN) and zinc hydroxyacetate (ZHA), using a coprecipitation method. The materials were characterized by X-ray diffraction (XRD), infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA), confirming the incorporation of the organic anion into the layered structure. DCBI and the host layers interact mainly through the CS₂ group. The compounds were evaluated as accelerators in the vulcanization of rubber and compared to the commercial accelerator ZEDC. The synthesized materials led to slower vulcanization reactions and vulcanizates with higher elongation at break and lower tear resistance. These features suggest that the materials may be suitable for applications that require greater flexibility and improved safety, presenting a promising alternative to conventional amine-based accelerators.</p> Graphical abstract <p>The vulcanization process was conducted with the interlayer materials synthesized in this work.</p> <p></p>
