  • Latex accelerator composition
    Patent number: 8673172
    Abstract: Accelerator composition for a rubber latex derived from a conjugated diene and optionally a vinyl aromatic comonomer including: (i) a diisopropyl xanthogen polysulphide (DIXP), (ii) an alkyldithiocarbamate wherein the alkyl chain contains from 5 to 20 carbon atoms, and (iii) diphenylguanidine (DPG), a curable aqueous synthetic rubber latex composition including said accelerator composition, a process for the water-based solvent-free manufacture of synthetic shaped synthetic elastomeric articles, prepared by using the accelerator composition.
