Automated ARGET ATRP Accelerates Catalyst Optimization for the Synthesis of Thiol-Functionalized Polymers.
Conventional synthesis of polymers by ATRP is relatively low throughput, involving iterative optimization of conditions in an inert atmosphere. Automated, high-throughput controlled radical polymerization was developed to accelerate catalyst optimization and production of disulfide-functionalized polymers without the need of an inert gas. Using ARGET ATRP, polymerization conditions were rapidly...
متن کاملARGET–ATRP Synthesis and Characterization of PNIPAAm Brushes for Quantitative Cell Detachment Studies
Stimuli responsive (or "smart") polymer brushes represent a non-toxic approach for achieving release of biofouling layers. Thermo-responsive poly(N-isopropylacrylamide) (PNIPAAm) polymer brushes have been shown to modulate bacterial adhesion and release through transition between temperatures above and below the lower critical solution temperature (LCST ~32 °C) of PNIPAAm in water. In this arti...
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 کاملEnzymatically Triggered, Isothermally Responsive Polymers: Reprogramming Poly(oligoethylene glycols) To Respond to Phosphatase.
Polymers which can respond to externally applied stimuli have found much application in the biomedical field due to their (reversible) coil-globule transitions. Polymers displaying a lower critical solution temperature are the most commonly used, but for blood-borne (i.e., soluble) biomedical applications the application of heat is not always possible, nor practical. Here we report the design a...
متن کاملSynthesis of some network polymers with siloxane units as a drug delivery system
New biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-ASA) in the main chain were prepared by ter polymerization of methacrylic acid (MA), 2-hydroxyethylmethacrylate (HEMA), and bis (trimethylsilyloxy) methylsilane (VBM) in the presence of some new cross-linking agents.The monomers and polymers were characterized by FT-IR and 1H-NM...
