A simple synthesis of poly(methylsilyne) has been developed. The straightforward polymerization reaction can be accomplished using simply a series of batteries and a very simple electrolyte. Poly(methylsilyne) has previously been shown to be a high-purity, high-yield precursor to stoichometric silicon carbide. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 112: 3519-3521, 2009


Electropolymerization of a New 4-(2,5-Di-2-thiophen-2-yl-pyrrol-1-yl)-Tetra Substituted Nickel Phthalocyanine Derivative
Yavuz, Arzu; Carbas, Buket Bezgin; Aras, Leyla; Önal, Ahmet Muhtar (Wiley, 2011-10-15)
A new tetrakis 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl) substituted nickel phthalocyanine (NiPc-SNS) was synthesized and characterized by elemental analysis, Fourier Transform Infrared (FT-IR), and UV-vis spectroscopies. The electrochemical polymerization of this newly synthesized NiPc-SNS was performed in dichloromethane (DCM)/tetrabutylammonium perchlorate (TBAP) solvent/electrolyte couple. An insoluble film was deposited on the electrode surface, both during repetitive cycling and constant potential electr...
Thermal stability and decomposition mechanism of poly(p-acryloyloxybenzoic acid and poly(p-methacryloyloxybenzoic acid) and their graft copolymers with polypropylene, Part II
Cetin, S.; Tincer, T. (Wiley, 2008-04-05)
Thermal stability and decomposition mechanism of poly(p-acryloyloxybenzoic) acid (PABA), p-methacryloyloxybenzoic acid (PMBA), and their graft coproducts of PP were studied by differential scanning calorimetry, direct pyrolysis mass spectrometry, and TG/IR system, combined thermogravimetric analyzer, and FTIR spectrometer. The homopolymers and corresponding grafts were found to be stable in nitrogen atmosphere but started to decompose under atmospheric conditions when heated above 230 degrees C. PABA and PA...
An experimental study of the dipole moment of poly(dimethylsiloxane)
Küçükyavuz, Z; ALGHEZAWI, N (Elsevier BV, 1990-1)
The mean-square dipole moments of poly(dimethylsiloxane) chains have been determined from dielectric constant measurements on dilute solutions of the polymer in toluene and carbon tetrachloride at temperatures in the range 10–60°C. The temperature coefficient of the dipole moment ratio in toluene was found to be positive, qualitatively in agreement with the prediction of rotational isomeric state theory. The values of the mean-square dipole moment in carbon tetrachloride are higher than in toluene indicatin...
Kinetic study of the reaction between hydroxyl-terminated polybutadiene and isophorone diisocyanate in bulk by quantitative FTIR spectroscopy
Kincal, D; Özkar, Saim (Wiley, 1997-12-05)
A kinetic study of the reaction between a hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) was carried out in the bulk state by using quantitative Fourier transform infrared(FTIR) spectroscopy. The reaction is shown to obey a second-order rate law, being first order in both the HTPB and IPDI concentrations. The activation parameters obtained from the evaluation of kinetic data are Delta H-double dagger = 41.1 +/- 0.4 kJ mol, Delta S-double dagger = -198 +/- 2 J K-1 mol(-1) and E-a...
Liquid Crystal Templates Combined with Photolithography Enable Synthesis of Chiral Twisted Polymeric Microparticles
AKDENİZ, BURAK; Büküşoğlu, Emre (Wiley, 2019-08-01)
Liquid crystals (LC), when combined with photolithography, enable synthesis of microparticles with 2D and 3D shapes and internal complexities. Films of nematic LCs are prepared using mixtures of reactive (RM257) and non-reactive mesogens with controlled alignment of LCs at the confining surfaces, photo-polymerized the RM257 using a photomask, and then extracted the unreacted mesogens to yield the polymeric microparticles. The extraction results in a controlled anisotropic shrinkage amount dependent on the R...
