Preparation of a Bis-GMA-Free Dental Resin System with Synthesized Fluorinated Dimethacrylate Monomers
With the aim of reducing human exposure to Bisphenol A (BPA) derivatives in dentistry, a fluorinated dimethacrylate monomer was synthesized to replace 2,2-bis[4-(2-hydroxy-3-methacryloy-loxypropyl)-phenyl]propane (Bis-GMA) as the base monomer of dental resin. After mixing with reactive diluent triethyleneglycol dimethacrylate (TEGDMA), fluorinated dimethacrylate (FDMA)/TEGDMA was prepared and c...
متن کاملNuclear magnetic resonance spectra of Bis-GMA and Iso-bis-GMA.
2, 2-Bis [4- (2-hydroxy-3-methacryloyloxypropoxy) phenyl] propane (bis-GMA) is widely used in dentistry as a monomer of composite resin system and their bonding agents. Since bis-GMA is not purified, its isomers and some chemicals such as residual initiator remain in the commercial product. Bis-GMA and iso-bis-GMA were separated from bis-GMA monomer by HPLC. NMR spectra of both monomers were re...
متن کاملسنتز مشتقات اورتانی bis-gma
اغلب کامپوزیت ها مخلوط فیزیکی مواد هستند که جسم توقویت شده ای را نتیجه می دهند. هدف برتر این پروژه ساخت مواد دندانی از نوع کامپوزیت می باشد. کامپوزیتهای دندانی را غالبا با عناوین رزین های پرشده رزین کامپوزیت می نامند. این مواد در اواسط دهه 1960 شناخته شدند اصطلاح کامپوزیت دندانی به شکل مرسوم بیانگر مخلوطی از شیشه های سیلیکات با مونومرهای آکریلی است که پلیمریزاسیون آنها هنگام اختلاط با شیشه آغاز...
15 صفحه اولA novel MRI contrast agent synthesized by ion exchange method
Objective: In this study, the zeolite-coated iron oxide nanoparticles were evaluated as MRI contrast agent and effect of the nanocomposite synthesis method on MRI contrast was tested. Materials and Methods: Ion exchange method was used for synthesis of iron oxide-zeolite and the as prepared nanocomposite was characterized by XRD, FESEM and TEM. The nanocomposite toxicity in the cell culture, a...
متن کاملRheological Characterization of a Waterborne Organic Nanoparticle Dispersion
Organic nanoparticles of poly(styrene-co-maleimide) or SMI were synthesized in aqueous dispersion with a maximum concentration of 35 wt.% and are favorably applied in industrial coating processes. In order to evaluate the further processability and flow behavior of these nanoparticle dispersions, general rheological characterization under creep, oscillatory and rotational testing was done by ap...
