Lipase-catalyzed syntheses of telechelic polyesters
Telechelic polyesters have successfully been synthesized with lipasecatalyzed polymerization. The produced telechelics had a high degree of difunctionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. Two different types of lipase-catalyzed polymerizations were applied – ring-opening ...
متن کاملSynthesis of elastic biodegradable polyesters of ethylene glycol and butylene glycol from sebacic acid.
High molecular weight biodegradable polyesters were prepared from sebacic acid, ethylene glycol and butylene glycol through a simple non-solvent polycondensation with a low toxicity catalyst. The successful synthesis of the polyesters was confirmed by gel permeation chromatography, (1)H-nuclear magnetic resonance and Fourier transform-infrared spectroscopies and differential scanning calorimetr...
متن کاملSurface Coating of Red Blood Cells with Monomethoxy poly(ethylene glycol) Activated with Two Different Reagents
Methoxy poly(ethylene glycol) (mPEG) with molecular mass of 5 kDa activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (RBCs). Inhibition of agglutination by blood-type specific antisera (anti-D) was employed to evaluate the effect of the polymer coating. The remaining single cells after incubation with anti-D sera were cou...
متن کاملPoly(ethylene glycol)-lipase complex highly active in ionic liquids
INTRODUCTION A number of studies on enzymatic reactions have been carried out in organic media. These reactions have several benefits compared with conventional organic synthesis, including high enantioselectivity, substrate specificity and low energy consumption. There are, however, several drawbacks in using organic solvents. Volatile organic solvents are often flammable and toxic to the envi...
متن کاملEthylene glycol-assisted coating of titania on nanoparticles.
Coating titania shells onto sub-micron sized particles has been widely studied recently, with success mainly limited to objects with sizes above 50 nm. Direct coating on particles below this size has been difficult to attain especially with good control over properties such as thickness and crystallinity. Here we demonstrate that titanium-glycolate formed by reacting titanium alkoxide and ethyl...
