چکیده

Efficient reduction of migration of di(2-ethylhexyl) phthalate (DEHP) is challenging because migration ofDEHP poses a serious threat to human health and the ecosystems. In the present study, water-insoluble β-cyclodextrinbased polyester (β-CDPE) was synthesized by reaction of β-cyclodextrin with sebacoyl chloride (SCl) as a cross-linkerusing micro-emulsion method. The β-CDPE was incorporated to PVC/DEHP systems (PVC/DCPEs) as a reactiveinhibitor to reduce DEHP migration. DEHP migration tests were carried out for the flexible PVC according to theISO3826:1993(E) test method and the quantity of migrated DEHP were then determined with UV-vis spectroscopy. Itwas found that the addition of β-CDPE decreases the levels of DEHP migration from the PVC/DCPEs samples byalmost 58.61%. Mechanical properties of PVC/ DCPEs films including the tensile strength (TS), Young’s modulus(YM) and elongation at break (EB) were investigated. All the mechanical data in PVC/DTCs samples were slightlyimproved in the presence of β-CDPE as compare to PVC/DEHP system

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
