The mechanical properties have been measured for Poly (vinyl chloride) (PVC)-Thermoplastic Polyurethane (TPU), -(Ethylene-vinylalchol) copolymer (EVOH), -Polyethylene (PE), -Poly (methyl methacrylate) (PMMA), binaly roll blends. The tensile properties for the PVC-PE, PVC-PMMA blend systems does not show the influence of metal soap as a stabilizer for PVC, while that for the PVC-TPU, PVC-EVOH blend systems does remarkably. In particulary, when the added Lead stearate (Pb-stear.) in blend systems, tensile strength have been significant decreased. It have been found by SEM and measured torque that Pb-stear, remarkably showed lubricative effect against TPU or EVOH. In result, it were occured in decreasing tensile strength because of that inhibite to disperse the polymer materials. In this way, it had become apparent that the effect of the metal soap on mechanical behavior of polymers should not be disregarded in running of roll process in polymer blends contained PVC.
