| Abstract | In this studypoly(butylene succinate) (PBS) , a polymeric plasticizer, was partially replaced aconventional plasticizer, diisononyl phthalate (DINP) to avoid the plasticizer loss from poly(vinyl chloride)(PVC) overtime for various service conditions and to obtain a long-term plasticizer retention in the flexiblePVC products. The plasticized PVC samples were prepared by melt mixing on a two roll mill, followed bycompression molding. The mechanical properties (tensile properties, tear strength and hardness), thermalstability and morphology of the 20/20 phr (parts by weight per hundred parts of resin) DINP/PBS-plasticizedPVC were evaluated and compared with those of the 40 phr DINP-plasticized PVC. The tensile strength,Young's modulus, tear strength, hardness and thermal stability were found to be improved, while theelongation at break was decreased as a result of the partial replacement of DINP with PBS in the plasticizedPVC. Moreover, the DINP/PBS-plasticized PVC composites filled with varied loadings of CaCO3 (2.5, 5,7.5 and 10 phr) showed an increase in the elongation at break, Young's modulus and thermal stability in adose-dependent manner, while the tensile strength, tear strength and hardness were unaffected by theincreasing amount of CaCO3. The morphology of the composites observed by scanning electron microscopyshowed a number of voids on the fractured surface of the plasticized PVC due to the pulling out CaCO3particles, caused by the low interfacial adhesion between filler and polymer. |
