β-Cyclodextrin Polymer Functionalized Magnetic Nanoparticle as a Novel Nano-inhibitor System in Flexible PVC Ahmad Raeisi, Khalil Faghihi Organic Polymer Chemistry Research Laboratory, Department of Chemistry, Faculty of Science, Arak University, ahmad.raeisi66@gmail.com The migration of phthalate plasticizers poses a serious threat to public health and the environment, because some of the phthalate series such as dioctyl phthalate (DOP) are suspected as endocrine disruptor and potential health risks may arise from its chronic exposure. Thus, an effective and practical approach is required for reducing DOP migration from plasticized PVC (P-PVC) [1,2]. In this study, we have synthesized a novel nano-inhibitor system, poly β-cyclodextrin conjugated magnetic nanoparticle (MNP-PCD) and explored its application in the efficient reduction of DOP migration from the P-PVC [3]. Migration tests of the flexible PVC were carried out according to the Organization for Standardization (ISO) 3826:1993(E) method, and the quantity of migrated DOP was then measured by using Gas chromatography (GC) and ultraviolet-visible (UV-vis) spectroscopy. From this result, it is observed that the synthesized novel nano-inhibitor system offers efficient interaction of poly β-cyclodextrin with DOP and effectively reduces the DOP migration from P-PVC (reduction efficiency was found to be 55 ~ 65%) without resulting in any serious changes in mechanical properties of plasticized PVC.
