Several different dihalophenylene oxide polymers prepared by thermal decomposition of halophenoxo copper complexes were studied in toluene using light scattering. For polymers of molecular weight around 5 × 104, those obtained from 4-bromo-2,6-dichlorophenoxide, 2-chloro-4,6-dibromophenoxide and 2,4,6-tribromophenoxide appear to be relatively linear with higher values of , whereas those obtained from 2,4,6-trichlorophenoxide and 2-bromo-4,6-dichlorophenoxide appear to have branched or condensed structures with lower values of . Values for the intrinsic viscosities and second virial coefficients were measured from ∼17 to 50°C for poly(dichlorophenylene oxides) synthesized from 2,4,6-trichlorophenoxide (Mw = 5.3 × 104) and from 4-bromo-2,6-dichlorophenoxide (Mw = 2.49 × 105). These quantities both pass through a maximum as the temperature increases.

Synthesis and characterization of conducting copolymers of (S)-2-methylbutyl-2-(3-thienyl)acetate with pyrrole and thiophene Levent, A; Toppare, Levent Kamil; Cianga, I; Yagci, Y (Wiley, 2003-05-30) Polymerization of methylbutyl-2-(3-thienyl)-acetate (MBTA) was achieved by constant current electrolysis at low temperature. Subsequently, the syntheses of block copolymers of polyMBTA were accomplished in the presence of either pyrrole or thiophene by constant potential electrolysis. Moreover, the copolymer of MBTA with thiophene was obtained with constant potential electrolysis.
Synthesis and characterization of poly(allyl methacrylate) obtained by gamma-radiation Vardareli, Tugba K.; Usanmaz, Ali (Wiley, 2007-04-15) Allyl methacrylate was polymerized by gamma-radiation under vacuum in solution and atom transfer radical polymerization (ATRP) methods and also in the presence of atmospheric oxygen in bulk. The kinetic curve is S-type with a longer induction period, because of the presence of oxygen, in bulk polymerization. The curve for the solution polymerization is almost linear with a short induction period. The rate started to decrease after about 60% conversion and reached to a limiting conversion of 100%. The polyme...
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, ...
Understanding the influence of hydrogen bonding and diisocyanate symmetry on the morphology and properties of segmented polyurethanes and polyureas: Computational and experimental study Sami, Selim; Yıldırım, Erol; Yurtsever, Mine; Yurtsever, Ersin; Yilgor, Emel; Yilgor, Iskender; Wilkes, Garth L. (Elsevier BV, 2014-09-02) Quantum mechanical calculations (QMC) and dissipative particle dynamics (DPD) siniulations were utilized to understand the nature of the short and long-range hydrogen bonding and its influence on the microphase morphology in segmented polyurethanes and segmented polyureas prepared without chain extenders through the stoichiometric reactions of hydroxy or amine terminated poly(tetramethylene oxide) (PTMO-1000) with 1,4-phenylene diisocyanate (PPDI) and 1,3-phenylene diisocyanate (MPDI). The possibility of lo...
Synthesis and characterization of conducting and non-conducting polymers of sodium 2,4,6-trichlorophenolate by microwave initiation Cakmak, O; Basturkmen, M; Kisakurek, D (Elsevier BV, 2004-07-22) A novel synthesis of poly(dichlorophenylene oxide) and a conducting polymer were achieved simultaneously from 2,4,6-trichlorophenol in a very short time, using microwave energy. The characterizations of poly(dichlorophenylene oxide) and the conducting polymer were performed by DSC, TGA, elemental analysis, FTIR, H-1 and C-13 NMR, SEM, MS and X-ray diffraction spectrometer analyses. The combined molecular weight of the polymer, 1.8 x 10(4), was determined by using viscometry measurement. Poly(dichlorophenyle...
