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 systemکلیدواژه ها

اطلاعات بیشتر در مورد COI
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.
