Abstract. Dicumyl peroxide (DCP)-cured thermoplastic vulcanizates (TPVs) based on blends of maleated ethylene propylene
rubber (m-EPM) and polypropylene (PP) using maleated-PP as a compatibilizer have been developed. Physical properties
of these TPVs change significantly with concentrations of DCP and rubber/plastic blend ratios. Important
correlations were obtained from rheometer delta torque values with various physical properties of the TPVs like tension set
and crosslink density etc. Wide angle X-ray diffraction study confirms that concentration of DCP has a strong influence on
the crystallinity of PP, which might affect the final physical properties of TPVs. The recyclability and ageing characteristics
of these TPVs are also found excellent
