The radiation-induced solid-state polymerization of acenaphthylene was carried out under vacuum at room temperature. The monomer and obtained polymer samples were investigated by UV, FTIR, DSC, TG, and powder X-ray diffraction methods to characterize the polymer and elucidate the polymerization mechanism. The polymer samples were crystalline with melting points ranging in 380-390 degrees C interval. Polymerization takes place through vinyl groups by a radical mechanism and crystal structure of monomer and polymer studied by powder X-ray diffraction were quite similar. The space group for both were P22(1)2 and cell parameters: a = 784.2 (6), b = 798.1(6), c = 1417.0(1) pm for monomer, and a = 791.7(8), b = 803.8(7), c = 1431.0(1) pm for polymer. The similarity of crystal structures shows a topotactic polymerization of monomer.

Topotactic solid-state polymerization of 3-aminocrotonamide by radiation
Usanmaz, Ali; Melad, OK (Wiley, 1996-04-30)
Radiation-induced solid-state polymerization of 3-aminocrotonamide (3-amino-2-butenamide) was carried out at room temperature, in open air atmosphere and under vacuum condition. The polymer obtained was white powder, soluble in methanol, but insoluble in water. The nature of polymers were investigated by IR, UV, x-ray, DP-MS, and elemental analysis to elucidate the mechanism of the polymerization. The polymer was crystalline with melting point in the range of 245-255 degrees C. The cell parameters and space...
Thermal degradation of poly(allyl methacrylate) by mass spectroscopy and TGA
Vardareli, Tugba Kantav; Keskin, Selda; Usanmaz, Ali (Informa UK Limited, 2006-10-01)
Allyl methacrylate, AMA was polymerized in CCl4 solution by alpha,alpha'-azoisobutyronitrile at 50 degrees C. The thermal degradation mechanism of PAMA was characterized by MS, TGA-FT-IR and FT-IR-ATR methods. The mass spectrum and TGA thermogram showed two stage degradation. The first stage of degradation was mostly linkage type degradation for the fragmentation of pendant allyl groups at 225 - 350 degrees C. In the second stage, at 395 - 515 degrees C, the degradation is random scission and depolymerizati...
Crystal structure effect in radiation induced solid state polymerization of methacrylamide
Usanmaz, Ali; Kafadar, AB (Informa UK Limited, 2004-01-01)
Radiation induced solid state polymerization of methacrylamide was carried out, opened to atmosphere and under vacuum conditions at room temperature. The white colored powder polymers obtained were insoluble in most common organic solvents such as carbon tetrachloride, dimethysulfoxide, acetone, etc. The polymers were characterized by IR, direct pyrolysis mass spectrometer (DP-MS), XRD, TGA, and DSC methods. The mechanism of the polymerization was elucidated from these results. There were no definite effect...
Reactive extrusion of poly(ethylene terephthalate)-(ethylene/methyl acrylate/glycidyl methacrylate)-organoclay nanocomposites
Alyamac, Elif; Yılmazer, Ülkü (Wiley, 2007-04-01)
This study was conducted to investigate the effects of component concentrations and addition order of the components on the final properties of ternary nanocomposites composed of poly(ethylene terephthalate), organoclay, and an ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer acting as an impact modifier for PET. In this context, first, the optimum amount of the impact modifier was determined by melt compounding binary PET-terpolymer blends in a corotating twin-screw extruder. The amount...
POLYMERIZATION OF 1-ETHYNYL-1-CYCLOHEXANOL BY RADIATION, ELECTROINITIATION, AND CHEMICAL CATALYSTS
Usanmaz, Ali; KIZILIRMAK, N (Informa UK Limited, 1992-01-01)
Solid-state polymerization of 1-ethynyl-1-cyclohexanol was carried out by irradiation in vacuum and in open air at 20-degrees-C. Radiation-induced polymerization was also done in a benzene solution. The products were mixtures of oligomers and polymers. IR, NMR, UV, and x-ray investigations showed the initial formation of trimer, oligomer, and polymer. The polymer fraction increased with an increase of conversion. Electroinitiated polymerization gave soluble and insoluble fractions. The soluble fraction was ...
