Photocatalyzed iron-based ATRP of methyl methacrylate using 1,3-dimethyl-2-imidazolidinone as both solvent and ligand
Photochemistry serves as a wonderful means to facilitate various chemical reactions and is indeed unique in its powerful ability to meet the energetic requirements for conducting processes that would not be accomplished using thermal counterparts. In this work, a novel photocatalyzed Fe-based atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) was performed under UV irradia...
متن کاملUse of alcohols as reducing agents for synthesis of well-defined polymers by AGET-ATRP.
Alcohols have been demonstrated to be efficient reducing agents for AGET-ATRP for the first time. Well-controlled polymerizations have been successfully achieved with the typical characteristics of "living"/controlled radical polymerization.
متن کاملAcetoxy-γ-valerolactone
Levulinyl cellulose esters have been produced as an effective renewable binder for architectural coatings. The title compound, C7H10O4 (systematic name: 2-methyl-5-oxo-tetra-hydro-furan-2-yl acetate), assigned as the esterifying species, was isolated and crystallized to confirm the structure. In the crystal, the mol-ecules pack in layers parallel to (102) utilizing weak C-H⋯O inter-actions.
متن کاملسنتز نانوکامپوزیت‌های پلی‌استیرن/MCM–41 به روش‌های AGET ATRP و ARGET ATRP
نانوکامپوزیت‌های پلی‌استیرن/MCM–41 به روش پلیمرشدن رادیکالی انتقال اتم (ATRP) در دمای 110 درجه سلسیوس سنتز شدند. روش‌های آغاز فعال‌کننده‌هایی که با انتقال الکترون تولید می‌شوند (AGET) و فعال‌کننده‌هایی که با انتقال الکترون بازتولید می‌شوند (ARGET) به عنوان دو روش نوین آغاز در ATRP به کار گرفته شدند. ساختار ویژه، مساحت سطح، اندازه ذرات و توزیع آنها و ساختار اسفنجی و حفره‌ای نانوذرات MCM–41 سنت...
متن کاملEthyl Maltol as a New Ligand for Spectrophotometric Determination of Iron
In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...
