Application of poly(butylenes succinate) as migration resistant plasticizer for poly(vinyl chloride)

The bio-based and biodegradable polyester poly (butylene succinate) (PBS) was successfully used as alternative plasticizers to modify poly (vinyl chloride) (PVC) in this work. The mechanical properties and plasticizing effect were estimated by the tensile strength, bending strength, bending modulus, hardness and the elongation at break of the PVC/PBS blends. And the migration stability of the PBS was investigated. It was showed that the migration-resistant property of PVC plasticized with PBS was greatly superior to that with dioctyl phthalate (DOP). Further, compatibility and dispersion of PBS in the matrix were excellent, indicating that the environmentally friendly PBS can be used as an alternative plasticizer to remove the potential health risks of migrating out phthalates during applications.
