Blends of poly(2,6-dibromo-1,4-phenylene oxide) (PDBrPO) with 4.8 mol % sulfonated polystyrene (4.8SPS), Na-neutralized 1.7 mol % sulfonated polystyrene (Na1.7SPS), Mn-neutralized 3.8 mol % sulfonated polystyrene (Mn3.8SPS), and Zn-neutralized 3.8 mol % sulfonated polystyrene (Zn3.8SPS) ionomers were investigated for their miscibilities with varying compositions by dilute solution viscometry (DSV), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). Deltab, mu, and alpha parameters by W. R. Krigbaum and F. J. Wall (J Polym Sci 1950, 5, 505), K. K. Chee (Eur Polym J 1990, 4, 423), and Z. Sun et al. (Eur Polyrn J 1992, 28, 1259), respectively, were calculated from DSV data to determine miscibility. Na1.7SPS is immiscible with PDBrPO in no relation to the blend compositions. On the other hand, the increasing extent of miscibility of the blends reflected by the data is as follows: 4.8SPS < Mn3.8SPS < Zn3.8SPS. DSC and SEM results are also in agreement with the DSV data except for the alpha parameter, which showed some disagreements with Deltab and mu parameters in a few blends.

Miscibility of methylmethacrylate-co-methacrylic acid polymer with magnesium, zinc, and manganese sulfonated polystyrene ionomers Alkan, C; Yurtseven, N; Aras, L (2005-01-01) The miscibility of methyl methacrylate-co-methacrylic acid polymer (MMA-MAA) with metal neutralized sulfonated polystyrene ionomers was investigated by viscometry, differential scanning calorimetry (DSC), and Fourier transform infrared radiation spectroscopy (FTIR) techniques. Polystyrene (PS) was sulfonated by acetic anhydride and sulfuric acid and the sulfonation degree was found to be 2.6 mole percent, and 2.6 mole percent sulfonated polystyrene was neutralized by Mg, Zn, and Mn salts. The miscibility be...
Compatibilization of poly(2,6-dimethyl-1,4-phenylene oxide) and poly(2,6-dichloro-1,4-phenylene oxide) with sulfonated polystyrene and its Na and Zn-neutralized ionomers Mih, M; Aras, L; Alkan, C (Springer Science and Business Media LLC, 2003-05-01) Compatibility of acidic (H), Na, and Zn neutralized sulfonated polystyrene ionomer blends with Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and Poly(2,6-dichloro-1,4-phenylene oxide) (PDCIPO) was investigated by Dilute Solution Viscometry (DSV) and Differential Scanning Calorimetry (DSC). The intrinsic viscosities of the blends, are measured in suitable solvents. The degree of compatibility of the blends is characterized by Ab parameter. According to the results, PPO is completely miscible, except for Na-ne...
Electrochemical polymerization and characterization of polyether-substituted aniline derivatives Tirkeş, Süha; Oenal, Ahmet M. (Wiley, 2007-08-01) New compounds consisting of aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry in an aqueous solution containing 3.0 moI L-1 H2SO4. Chemical polymerization was carried out using (NH4)(2)S2O8 as oxidizing agent. It was found that both methods gave the same polymer product without any cleavage of the polyether bridge between aniline rings. The polymers were characterized using the Fou...
Highly Crystalline Poly(L-lactic acid) Porous Films Prepared with CO2-philic, Hybrid, Liquid Cell Nucleators Culhacioglu, Yagmur; Hasırcı, Nesrin; Dilek Hacıhabiboğlu, Çerağ (2019-12-18) Supercritical CO2 (scCO(2)) foaming of poly(L-lactic acid) composite films with liquid polyhedral oligomeric silsesquioxanes (PLLA-POSS) was carried out to obtain polymer matrices for drug delivery applications. Highly crystalline (>45%) PLLA generally requires high supercritical processing (saturation) temperatures close to its melting temperature (similar to 450 K) and pressures about or over 20 MPa for foaming with scCO(2). To decrease the saturation temperature and obtain ductile PLLA films with uniform...
Microwave-assisted simultaneous novel synthesis of poly(dibromophenylene oxide)s, poly(diiodophenylene oxide)s (p), conducting(cp) and/or crosslinked (clp) and/or radical ion polymers (rip) Çelik, Güler Bayraklı; Kısakürek, Duygu; Department of Chemistry (2007) Microwave-assisted novel synthesis of poly(dibromophenylene oxide) or poly(diiodophenylene oxide) (P), conducting polymer (CP) and/or crosslinked polymer (CLP) and/or radical ion polymer (RIP) were achieved simultaneously from lithium, sodium or potassium 2,4,6-bromophenolate or sodium 2,4,6-iodophenolate in a very short time interval. Polymerizations were carried out by constant microwave energy with different time intervals varying from 1 to 20 min; or at constant time intervals with variation of microwav...
