Structure-Initiator Activity Dependence of Aminimides as Thermally Latent Initiators in the Polymerization of Glycidyl Phenyl Ether - Novel aminimides were synthesized from the corresponding carboxylic acid esters, 1,1-dimethylhydrazine, and epoxides in 54-95% yields. Bulk polymerization of glycidyl phenyl ether (GPE) with 3 mol % of the aminimides was evaluated by DSC as a model process. All the DSC curves showed no exothermic peaks below 120 (degree)C but showed sharp exothermic peaks above 137 (degree)C, which indicated the good thermal latency of the aminimides. Good relationships were observed between the calculated bond length from the carbonyl carbon to the a-carbon of the aliphatic group (R--C), DSC onset temperatures, and the thermal dissociation temperatures (Td) of the aminimides. The aminimide with a longer R--C bond length showed lower Td and DSC onset temperature, that is, higher activity/ 미리보기

Monochromatic-Red-Light Emission of Novel Copolymers Containing Carbazole Units and Europium-Acrylate Complexes - Nearly monochromatic-red-light-emitting polymers with pendant carbazole and europium (Eu) complex were synthesized and characterized by Fourier transform infrared, elemental analysis (EA), 1H NMR, 13C NMR, UV, and gel permeation chromatography. The photoluminescence and electroluminescence (EL) properties of these polymers were investigated. A single-layer light-emitting-diode device of the structure (indium tin oxide/polymer P4/Al) was fabricated, showing 520 the characteristic bright-red EL of the Eu3+ complex at 614 nm at a turn-on voltage of about 17 V. The EL spectrum, current-voltage, and emission-intensity-voltage characteristics of the device were measured/ 미리보기

Solvent Removal During Curing Process of Highly Spheric and Monodispersed-Sized Polystyrene Capsules from Density-Matched Emulsions Composed of Water and Benzene/1,2-Dichloroethane - For the curing process of highly spheric monodispersed 4-mm-in-diameter polystyrene capsules with uniform thickness from W/O/W emulsions, the masses of the solvents were measured for the oil phases and the distillate and calculated for the water phase. The analysis of the solvents in the water phase indicated that the process was governed by the kinetics of their dissolving from the oil phase to the outer water phase rather than by the vapor pressure of the solvents in the early stage before the oil phase lost its fluidity. In order to prepare the capsules by this method, the solubility of the solvents in water is crucial/ 미리보기

Reaction of p-Toluenesulfonyl Isocyanate with Polymers Having Amide Moieties and Hydrolysis of the Obtained Polymers - The chemical modification of polymers having amide moieties was carried out with p-toluensulfonyl isocyanate. The resulting polymers revealed high hydrolytic character. For example, poly(acrylamide) was refluxed with an excess amount of p-toluenesulfonyl isocyanate in THF for 50 h to obtain a structurally modified polymer in 76% yield, whose sulfonylurea functionality was 100%. The resulting polymer was subjected to hydrolysis in a 1 M NaOH solution at 50 (degree)C to convert 90% of the sulfonylurea in the side chain to the carboxylic acid moieties/ 미리보기

Solid-Phase Thermal Polymerization of Macrocyclic Ethylene Terephthalate Dimer Using Various Transesterification Catalysts - Solid-phase thermal ring-opening polymerization of macrocyclic ethylene terephthalate dimer with and without catalyst was investigated for the first time. 1,3-Dichloro-1,1,3,3-tetrabutyldistannoxane exhibited the highest catalytic activity, and a colorless polymer with a weight-average molecular weight of 36,100 was obtained in 100% yields by heating for 3 min at 200(degree) C/ 미리보기

Wavelength-Selected Radiothermoluminescence of Polyethylene Doped with Pyrene - Radioluminescence from electron-irradiated polyethylene doped with pyrene was investigated in the temperature range of 77-273 K. The spectra of emitted light were recorded and temperature dependences of radioluminescence intensities at chosen wavelengths were examined using a wavelength selected radiothermoluminescence technique. The experimental results were explained in terms of an electron-solute radical cation and solute radical ions recombination. Pyrene-excimer emission was observed in the glass transition temperature range of the polyethylene matrix/ 미리보기
