Study on Recrystallization Process of Poly(DL-lactide)/Poly(ethylene glycol) Diblock Copolymer
نویسندگان
چکیده
Poly (DL-lactide)/Poly (ethylene glycol) diblock copolymer is successfully synthesized with mPEG and DL-LA as main raw materials, the residual monomers of polymer were removed by recrystallization. FT-IR used to characterize structure polymer. Gas chromatography determine solvent The solubility in different solvents was determined, effect systems on removal discussed. results showed that Poly(DL-lactide)/Poly(ethylene recrystallized acetone/ isopropyl ether system has best ability remove monomers, obtained are less than 0.01 wt%, total only 0.24 productivity high 95.5 wt%.

10 11 Both visible and infrared (IR) spectroscopic ellipsometry have been employed to study the 12 structure of thin layers of bovine submaxillary mucin (BSM) adsorbed on poly(acrylic acid13 block-methyl methacrylate) (PAA-b-PMMA) copolymer and poly(methyl methacrylate) 14 surfaces at three pH values (3, 7 and 10). The adsorbed mucin layer on the copolymer surface 15 had the greatest thickness ...

2014 At equilibrium thin films of symmetric diblock copolymers exhibit a morphology where the lamellar microdomains are oriented parallel to the external surfaces. Interference microscopy has been used to investigate this orientation which results in a quantization of the film thickness. Solution cast films of the symmetric polystyrene/polymethylmethacrylate P(S-b-MMA) diblock copolymers exhibi...

Steel 2205 is one of the most famous duplex stainless steels. The microstructure of this steel composed of ferrite and austenite in similar amount. Therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. It is not possible to employ the usual heat treatment. It shows the importance of ...
