Polymerization of 3-aminocrotonamide has not been reported before. It was polymerized by radiation in the solid-state to obtain a crystalline polymer which has a similar crystal structure to that of the monomer. In this work the structure and mode of monomer addition in the polymer chain were investigated by mass spectroscopy. The data indicated that the addition of monomer molecules takes place by a condensation process with evolution of 2n - 1 NH3 molecules for each 2n monomer molecules. The highest yield of thermal degradation products was obtained at 246° during the direct pyrolysis of the polymer.

RADIATION-INDUCED AND ELECTROINITIATED POLYMERIZATION OF ALLYLBENZENE SOUSY, K; USANMAZ, A; Önal, Ahmet Muhtar (Elsevier BV, 1990-08-01) Radiation-induced and electroinitiated polymerization of allylbenzene has been investigated. Radiation-induced polymerization at room temperature was found to give mainly dimers and trimers with a maximum yield of 5%. Electroinitiated polymerization of the monomer yielded insoluble polymer films on the surface of the anode together with low molecular weight polymers in the bulk solution. The effects of temperature and monomer concentration on the rate of electroinitiated polymerization were also studied. Th...
Immobilization of glucose oxidase and urease in hydrogel matrices Gurel, I; Arica, MY; Hasırcı, Vasıf Nejat (1997-01-01) Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, retention of activities and swelling rates was obtained. To optimize the system, duration of exposure, reaction temperature, co-monomer concentrations, initiator and cross linker compositions were varied. The repeated reusability of the generated products was also tested. It was found...
Adsorption of dithiophosphate and dithiophosphinate on chalcopyrite Guler, T; Hicyilmaz, C; Gokagac, G; Ekmeci, Z (Elsevier BV, 2006-01-01) Electrochemical behavior of chalcopyrite was investigated in the absence and presence of dithiophosphate (DTP) and dithiophosphinate (DTPI), selective thiols against Fe-sulfides in the flotation of sulfide ores, in potentiostatically controlled electrochemical condition. Diffuse reflectance Fourier transformation (DRIFT) spectroscopy was applied to determine the type of adsorbed collector species, and Hallimond tube flotation tests were performed to clarify the role of polarization potential and thiol colle...
LEPTON NUMBER VIOLATION DECAYS IN E6 STRING MODEL Alıyev, Tahmasıb; CETIN, Y; SILAHTAROGLU, E (Springer Science and Business Media LLC, 1994-08-01) Lepton number violation decays l(i) --> l(j)gammagamma and l(j) --> 3l(j) are investigated in the framework of E6 superstring model and the explicit expression for these decay rates are obtained. Relations between lepton number violation decays l(i) --> l(j)gammagamma and l(i) --> l(j)gamma are established and it is shown that the relative value of these decays is independent of the details of the considered model. In the considered model we predict that BR(tau --> mugammagamma) is large than BR(mu --> egam...
Defect characterization in Bi12GeO20 single crystals by thermoluminescence Delice, S.; Isik, M.; Sarıgül, Neslihan; Hasanlı, Nızamı (2021-05-01) Bi12GeO20 single crystal grown by Czochralski method was investigated in terms of thermoluminescence (TL) properties. TL experiments were performed for various heating rates between 1 and 6 K/s in the temperature region of 300-675 K. One TL peak with peak maximum temperature of 557 K was observed in the TL spectrum as constant heating rate of 1 K/s was employed. Curve fitting, initial rise and variable heating rate methods were applied to calculate the activation energy of trap level corresponding to this T...
