Micelles of polybutadiene-b-poly(ethylene oxide) in methanol, cyclohexane, and methanol + cyclohexane.
We have studied the self-assembly of a polybutadiene-b-poly(ethylene oxide) diblock copolymer in methanol, in cyclohexane, and in the partially miscible binary mixture of methanol + cyclohexane. Molecular probe experiments indicated that PB(89)-b-PEO(132) (subscripts indicate the number of monomers in each block) forms micelles with PEO cores and PB coronas in pure cyclohexane and micelles with...
متن کاملFabrication of Two Polyester Nanofiber Types Containing the Biobased Monomer Isosorbide: Poly (Ethylene Glycol 1,4-Cyclohexane Dimethylene Isosorbide Terephthalate) and Poly (1,4-Cyclohexane Dimethylene Isosorbide Terephthalate)
The thermal and mechanical properties of two types of polyester nanofiber, poly (1,4-cyclohexanedimethylene isosorbide terephthalate) (PICT) copolymers and the terpolyester of isosorbide, ethylene glycol, 1,4-cyclohexane dimethanol, and terephthalic acid (PEICT), were investigated. This is the first attempt to fabricate PICT nanofiber via the electrospinning method; comparison with PEICT nanofi...
متن کاملTemperature dependence of hydrodynamic lengths in the polystyrene-cyclohexane system
2014 We present experimental data on the dynamic temperature behaviour of the polystyrene-cyclohexane system in the neighbourhood of the 03B8 point (0 ~ T 2014 03B8 30 °C). It is found that the temperature dependence of the hydrodynamic radii RH and 03BEH of a chain in dilute regime and a blob in semi-dilute regime are respectively : RH ~ (T 03B8)0.034±0.005 03BEH ~ (T 03B8)-0.33±0.04 . We show...
متن کاملHigh-resolution 19F and 1H NMR of a vinylidenefluoride telomer
The reaction products of vinylidenefluoride (VDF) with methanol as a telogen have been analysed in the solution state by H and F nuclear magnetic resonance (NMR). Highresolution F and H NMR spectra were achieved using high-power H and F decoupling respectively, giving superior resolution and revealing previously unresolved signals of the vinylidenefluoride telomer (VDFT). H and F homoand hetero...
متن کاملSetting Cyclohexane Stereochemistry with Oxidation
Thanks to its atomand step-economy, C–H bond oxidation represents a “hot topic” in synthetic chemistry. However, due to the ubiquity of such bonds in organic molecules, regioand enantioselective C–H bond oxidation turns out to be extremely challenging, and efficient direct methods are in high demand. Compared to the success of aliphatic sp C–H oxidation by enzymes (such as cytochrome P450, Figu...
