Di-2-ethyl hexyl phthalate (DOP) and di-2-ethyl hexyl adiphate (DOA) were mixed with poly(vlnvl chlorides) [PVC] which have different degrees of polymerization (DP). Tensile strength, elongation, density, abrasion resistance, and hardness of these compounds were measured, High molecular weight PVC(DP 2500) was superior to that of DP 1300 for tensile strength, Hardness. But elongation and abrasion resistance of P1300 systems were better than those of P2500 systems. The densities of both systems were almost same. On the other hand, DOP Plasticized PVC was superior to DOA plasticized one for tensile strength, elongation, hardness. In cases of density, abrasion resistance, and flexual resistance, DOA systems were better than those of DOP systems.
