Abstract Elastomeric chlorosulfonated polyethylene (Hypalon) and thermoplastic polypropylene (PP) based
thermoplastic Vulcanizates (TPVs) were prepared in presence of different doses of partial
methyl ester of styrene-maleic anhydride copolymer (PMES-MA) as compatibilizer employing
dynamic vulcanization technique. The mechanical analysis of the prepared TPVs exhibited
significant improvements in stress at 25% modulus, ultimate tensile strength (UTS), and
hardness values. FTIR studies revealed that a chemical interaction had taken place between
hypalon and compatibilizer during the process of dynamic vulcanization which led to an
enhancement of interfacial adhesion between them. The two-phase morphologies were clearly
observed by scanning electron microscopic studies. The Tg values… More >
