The synthesis of poly(dihalophenylene oxide)s by thermal decomposition of Fe(II), Ce(III) and Ce(IV) phenolato complexes with pyridine as neutral ligands were achieved at different temperature ranges (140 degrees - 250 degrees C) with different time intervals (3 - 48 hr) via atom transfer rearrangement radical polymerization (ATRRP). The complexes were characterized by FTIR, DSC, UV-Visible, mass spectroscopy, magnetic susceptibility and elemental analyses. Structural analyses of polymers were performed by H-1 and C-13-NMR, FTIR spectroscopic analyses, T-g by DSC and the molecular weights by viscometrical method. H-1-NMR spectra of polymers are quite similar in pattern except the relative intensities of two main peaks, all having branched structures. The lowest percent conversion values were observed for polymers synthesized from Fe(III) complexes compared to Ce(III) and Ce(IV) complexes. The glass transition temperature of the polymers were quite high indicating they are rigid polymers (162 degrees to 187 degrees C).

Atom transfer rearrangement radical polymerization of diammine-bis(2,4,6-trihalophenolato)copper(II) complexes in the solid state Goekagac, Guelsuen; Sonsuz, Muammer; Sen, Fatih; Kisakuerek, Duygu (Walter de Gruyter GmbH, 2006-10-01) The synthesis of the poly(dichloro- or dibromophenylene oxide)s was achieved by the thermal decomposition of diammine-bis(2,4,6-trihalophenolato)copper(II) complexes in the solid state by atom transfer rearrangement radical polymerization. The thermal decomposition was performed either at different temperature ranges, 110-250 degrees C, for 3 h, or at the maximum conversion temperature for different time intervals, 3-48 h. Maximum yields of polymers were obtained at 190 degrees C and 3 h. The polymers were ...
Phase Behavior of Carbon Dioxide and Polyhedral Oligomeric Silsesquioxanes with Two Different Functional Groups Dumanlilar, Beril; Dilek Hacıhabiboğlu, Çerağ (Elsevier BV, 2020-09-01) Phase behavior of carbon dioxide and polyhedral oligomeric silsesquioxanes (POSS) modified with two different functional groups is studied in the temperature range of 308-323 K, up to 22 MPa. Different than the common types, one of the eight functional groups attached to the Si atoms of these POSS is a CO2-philic functional group, methacryl, while the rest are branched alkyl chains, either isooctyl (MIOPOSS) or isobutyl (MIBPOSS). Methacrylisobutyl POSS-CO2 binary system exhibits pressure-induced melting te...
INTRAZEOLITE SEMICONDUCTORS - NA-23 MAS NMR, TL+ LUMINESCENCE QUENCHING, AND FAR-IR STUDIES OF ACID-BASE PRECURSOR CHEMISTRY IN ZEOLITE-Y MCMURRAY, L; HOLMES, AJ; KUPERMAN, A; OZIN, GA; Özkar, Saim (American Chemical Society (ACS), 1991-11-01) Proton-loaded zeolites, prepared from fully dehydrated zeolites and gaseous, anhydrous Bronsted acids, represent an important step in the synthesis of intrazeolite semiconductor quantum supralattices. Adsorption-induced Na-23 MAS NMR chemical shifts, far-IR Na+ and Tl+ translatory mode frequency shifts, and Tl+ luminescence quenching effects were chosen as probes of cation-anion interaction in these materials. Samples of zeolite Y with various loadings of Tl+ were prepared via aqueous ion-exchange techniq...
INTRAZEOLITE TOPOTAXY - NA-23 DOUBLE-ROTATION NMR-STUDY OF TRANSITION-METAL HEXACARBONYLS AND OXIDES ENCAPSULATED IN SODIUM ZEOLITE-Y JELINEK, R; Özkar, Saim; OZIN, GA (American Chemical Society (ACS), 1992-07-01) Na-23 double-rotation NMR (DOR) provides details on site specific adsorption and anchoring interactions in intrazeolite hexacarbonylmetal(0) complexes, M{M(CO)6}-Na56Y, where M = Mo and W, and their molecular photooxidation products, n{MO3-x}-Na56Y, over the full composition range 0 < m less-than-or-equal-to 16, 0 < n less-than-or-equal-to 32 and 0 less-than-or-equal-to x less-than-or-equal-to 1. The shifts, intensities, and line shapes of the Na-23 DOR resonances carry information on the environments of th...
Synthesis of poly(dihalophenylene oxide)s by atom transfer radical rearrangement polymerization via Ce(IV)/Ce(III) complexes in solid state Çelik, Güler (Informa UK Limited, 2006-01-01) Poly(dihalophenylene oxide)s by solid-state thermal decomposition of (trihalophenolato) cerium complexes with either N-methyl imidazole or pyridine as neutral ligands were synthesized at different temperatures (80-250 degrees C) and different time intervals (3-48 h) via atom transfer rearrangement radical polymerization. The complexes were characterized by FT-IR, DSC, SEM, mass spectroscopy, magnetic susceptibility and elemental analyses. Structural analyses of polymers were performed by H-1- and C-13-NMR, ...
