Preparation and characterization of biocompatible poly(L‐lactic acid)/gelatin blend membrane
Authors: Zhao Xiaodong , Liu Wenguang , Yao Kangde 
Published: April 2006

AbstractPoly(L‐lactic acid) (PLLA)/gelatin blend membranes were prepared by solution casting method and using dimethyl sulfoxide (DMSO) as a cosolvent. Scanning electron microscopy measurement indicated that when the amounts of gelatin in PLLA/gelatin blend membranes are less than 5%, the sizes of phase separation of gelatin are in range of several hundred nanometers. These benefit in retaining the strength of PLLA membranes. X‐ray diffraction analysis revealed that the semicrystalline PLLA became amorphous and the melt temperature of crystalline PLLA changes from 56 to 38°C after it was processed in DMSO solvent. When the content of gelatin is less than 5%, the films not only retain a good mechanical property but also improve the hydrophilicity of PLLA. The molecular motion of PLLA in blend films were also investigated by solid state 13C CP/MAS NMR. On the basis of the result of relaxation times, it was found that the molecular motion of PLLA100 and PLLA/gelatin blends increased when compared with that of original PLLA. It was further verified that semicrystalline PLLA became amorphous. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 269–276, 2006

Authors: Mart H. , Sökmen T. , Yürük H. 
Published: April 2006

AbstractPolymerization of 3‐hydroxybenzaldehyde was investigated by oxidative polycondensation (OP) method. No polycondensation reaction was observed both in acidic (in CH3COOH) and organic (in THF) media. Polycondensation was carried out with hydrogenperoxide (H2O2) in an aqueous alkaline medium at 90°C. The product was characterized by 1H NMR, 13C NMR, FTIR, UV–vis, and elemental analysis. The number average molecular weight, mass average molecular weight, and polydispersity index values of O‐3HBA were found to be 3600, 8000 g mol−1, and 2.22, respectively. The product (O‐3HBA) with reactive aldehyde and hydroxyl group was soluble in most polar organic solvents and was composed of phenylene units. Thermal properties of the oligomer were investigated by thermogravimetric analyses under an air atmosphere. The weight loss of O‐3HBA was found to be 5 and 50% at 231 and >1000°C, respectively. The carboneous residue of the O‐3HBA was 54% at 1000°C. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 892–897, 2006
Kinetics of natural rubber vulcanization in the end stage of curing period
Authors: Wang Ping‐Yue , Qinn Hong‐Lian , Yu He‐Ping 
Published: April 2006

AbstractIt was found that the change of vulcameter torque in the end stage of curing period of natural rubber does not follow first‐order kinetics and can be expressed in a kinetic equation of . The reaction order n calculated by the above equation is in the range of 0.68–0.74. The rate constant of the end stage increases with a rise in temperature and is well satisfied with Arrherius equation, giving activation energy E = 79.321 kJ/mol. If whole curing period is treated by first‐order kinetics without a change of reaction order from n = 1 to n = 0.68–0.74, the values of torque in the end stage of curing period predicted with first‐order kinetics equation will be lower than that obtained from vulcameter. © 2006 Wiley Periodicals, Inc.

Antibody purification using porous metal–chelated monolithic columns
Authors: Bereli Nilay , Uzun Lokman , Yavuz Handan , Elkak Assem , Denizli Adil 
Published: April 2006

AbstractA novel monolithic material was developed to obtain efficient and cost‐effective purification of IgG from human plasma. The porous monolith was obtained by bulk polymerization in a glass tube of 2‐hydroxyethyl methacrylate (HEMA) and N‐methacryloyl‐(L)‐histidine methyl ester (MAH). The poly(HEMA‐MAH) monolith had a specific surface area of 214.6 m2/g and was characterized by swelling studies, porosity measurement, FTIR, scanning electron microscopy, and elemental analysis. Then the monolith was loaded with Cu2+ ions to form the metal chelate. Poly(HEMA‐MAH) monolith with a swelling ratio of 74% and containing 20.9 μmol MAH/g was used in the adsorption/desorption of IgG from aqueous solutions and human plasma. The maximum adsorption of IgG from an aqueous solution in phosphate buffer was 10.8 mg/g at pH 7.0. Higher adsorption was obtained from human plasma (up to 104.2 mg/g), with a purity of 94.1%. It was observed that IgG could be repeatedly adsorbed and desorbed with the poly(HEMA‐MAH) monolith without significant loss of adsorption capacity. © 2006 Wiley Periodicals, Inc.

Characteristics and kinetics of degradation of polystyrene in supercritical water
Authors: Kwak H. , Shin H.‐Y. , Bae S.‐Y. , Kumazawa H. 
Published: April 2006

AbstractThe degradation of polystyrene (PS) in sub‐ or supercritical water was carried out at reaction temperatures ranging from 370°C to 420°C and pressures of 240 to 320 bar. At 370°C, where water is in a subcritical state, the degradation was in equilibrium in about 5 min, whereas at 380°C and 390°C, where water is in a supercritical state, it was completed in 15 and 3 min, respectively. The equilibrium conversion in the supercritical state (100 wt %) was higher than that in the subcritical water (ca. 80 wt %). The dependence on time of selectivity for the degradation products—styrene monomer, styrene dimer, styrene trimer, toluene, ethyl benzene, isopropyl benzene, and triphenyl benzene—were investigated at 400°C and 280 bar. As the reaction proceeded, selectivity for styrene monomers, dimers, and trimers decreased, whereas that for toluene, ethyl benzene, and isopropyl benzene increased because of the difficulty of decomposing the benzene rings and phenyl radicals. Triphenyl benzene increased with reaction time for the same reason. With increasing temperature, selectivity for the styrene monomers and dimers decreased slightly, whereas selectivity for toluene and ethyl benzene increased a little. The kinetic behavior of PS in supercritical water along with supercritical acetone and n‐hexane were investigated. The degradation processes of PS in such supercritical fluids could be formulated by the first‐order kinetic law at the initial stage of the reaction. The activation energy for the degradation in supercritical water was evaluated to be 157 kJ/mol compared to an activation energy of 132 kJ/mol in the supercritical n‐hexane. © 2006 Wiley Periodicals, Inc.

Small molecule desorption prior to dissolution of a polymeric glass
Authors: Pekcan Önder , Uğur Şaziye 
Published: April 2006

AbstractPoly(methyl methacrylate) (PMMA) discs in various molecular weights (Mw) were prepared by free‐radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state fluorescence experiments were performed to monitor desorption processes in chloroform solvent. When the PMMA discs were in chloroform, desorption of Py molecules were monitored by observing the change of Py fluorescence intensity IP. To understand the mechanism of desorption, two different experiments were carried out in the meantime. In the first experiment, the weight of swelling and dissolving PMMA discs against dissolution time was monitored. The parallel experiment was conducted by measuring fluorescence intensity IP from the desorbing Py molecules. Then, a set of desorption experiments were performed by monitoring IP for various discs with different molecular weight of PMMA. A Fickian diffusion model was employed to quantify the fluorescence data produced from the swelling PMMA discs to measure desorption coefficients Dd. The measured Dd values decrease as the molecular weight of PMMA is increased in the swelling glass. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 908–912, 2006
Effects of heat treatment on tensile properties of diacetate fibers
Authors: Zhang Jing , Huang Li‐Qian , Wang Shan‐Yuan 
Published: April 2006

AbstractDiacetate filaments were heat‐treated (without tension or with tension) under dry‐heat or wet‐heat environment, respectively. The effects of temperature, time, and tension on tensile properties of diacetate fibers after heat treatments were discussed. The results show that diacetate fibers present no obvious improvement on its tensile properties after dry‐heat treatments without tension. It was also found that during dry heat treatments with tension, the increase in tensile properties of fibers mainly depends on temperature and tension. Moreover, being dry‐heat treated with tension instant after wet‐heat treatment without tension, diacetate fibers exhibit a higher improvement on its tensile properties comparing with dry heat method with tension. The shrinking measurement for the fibers indicates different supermolecular structures were developed in the fiber before treatment and after treatment, which leads to the different extent in the improvement of tensile properties for the fibers. © 2006 Wiley Periodicals, Inc.

Published: April 2006

AbstractPoly(para‐phenylene)s (PPPs) are an interesting class of rigid‐rod polymers that have excellent thermal and mechanical properties. Because of their high degree of crystallinity and lower permeability to methanol, PPPs are insoluble and infusible. A number of methods have been developed to synthesize substituted sulfonated PPPs bearing lateral chains to improve their solubility. In this work, a comparison of the physicochemical properties of three PPP‐based polymers is made with respect to Nafion membranes. One of these polymers was prepared with the postsulfonation method, and the other two were made with a new method of grafting developed in the Commissariat à l'Energie Atomique laboratory (a grafted sulfonated PPP polymer and a grafted perfluorinated sulfonated polymer). The sulfonated PPP polymers were examined for their mechanical properties, small‐angle X‐ray scattering, water absorption, proton conductivity, and methanol permeability. Relations between structures and properties were also investigated. Performances in fuel‐cell tests were also investigated. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 944–952, 2006
