Methyl methacrylate (MMA) was polymerized by the atom transfer radical polymerization (ATRP) method to obtain living low molecular weight polymers. The initiator was p-toluenesulfonylchloride and the catalyst ligand complex system was CuCl-4,4'dimethyl 2,2'bipyridine. Polymers with controlled molecular weight were obtained. The polymer chains were shown by NMR spectrum to be mostly syndiotactic. The molecular weight distributions were measured by the GPC method. The K and a constants in [eta] = KM alpha equation were measured as 9.13 x 10(-5) and 0.74, respectively. FT- IR and X-Ray results showed steororegularity in polymer chains. The thermal properties were studied by DSC and molecular weight-glass transition temperature relations were determined.

Electrochromic properties of 'Trimeric' thiophene-pyrrole-thiophene derivative grown from electrodeposited 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine and its copolymer Tarkuc, Simge; Ak, Metin; Onurhan, Erdal; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01) A centrosymmetric polymer precursor, namely 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine (TPHA), was synthesized via a Knorr-Paal reaction using 1,4-di(2-thienyl)-1,4-butanedione and hexane-1,6-diamine. The resultant monomer was characterized by Nuclear Magnetic Resonance (H-1-NMR). Electroactivity of TPHA was investigated via cyclic voltammetry. The electronic structure and the nature of electrochromism in P(TPHA) and its copolymer with EDOT, (P(TPHA-co-EDOT)), were examined via spectroelectrochem...
Carbothermic formation of boron nitride Aydogdu, A; Sevinc, N (Elsevier BV, 2003-01-01) Formation of boron nitride by reaction of boric oxide with carbon and nitrogen was studied. It was found from the results of experiments conducted by holding BA-activated C mixtures under a flowing nitrogen atmosphere that formation of boron nitride was complete in 120 min at 1500 degreesC. After cleaning the reaction product from the ash of the activated carbon and from the unreacted B2O3 pure BN powder was obtained. B4C was found to exist as an intermediate species in the reaction products of the experime...
Conducting Polymer Composites of Multiwalled Carbon Nanotube Filled Doped Polyaniline Yilmaz, Faris; Kucukyavuz, Zuhal (Wiley, 2009-01-15) A multiwalled carbon nanotube (c-MWNT)/polyaniline (PANI) composite was synthesized by an in situ chemical oxidative polymerization process. With the carbon nanotube loading increased from 0 to 30 wt %,, the conductivity also increased and became weakly temperature-dependent. Fourier transform infrared spectroscopy studies showed that the synthesis by an in situ process led to effective site-selective interactions between the quinoid ring of the PANI and the multiwalled nanotubes, facilitating charge-transf...
Stereoregularity of fractionally crystallized poly(propylene oxide) samples by 13C-NMR spectroscopy Alyürük, K.; Alyürük, Kemal (Wiley, 1989-4) Several stereoregular poly(propylene oxide) (PPO) samples were synthesized employing either trimethyl aluminum hydrolyzates or Pruitt–Baggett type catalysts. Dilute isooctane solutions of these samples were fractionally crystallized by stepwise cooling from 333 K down to 273 K. The fractions which dissolve at 273 K were noncrystallizable and were further fractionated by GFC. The isolated fractions were characterized by 13C‐NMR, DSC, and viscometry techniques. Both structural (head‐to‐head and tail‐to‐tail l...
Combustion synthesis of calcium phosphate bioceramic powders Tas, AC (Elsevier BV, 2000-12-01) Calcium phosphate (hydroxyapatite and tri-calcium phosphate) bioceramics closely resembling, in chemical composition, those found in vivo in human bones have been synthesized by using novel synthetic body fluid solutions via the self-propagating combustion synthesis (SPCS) method. Powder characterization was performed by XRD: ICP-AES, FTIR and SEM.
