A comparison study: The new extended shelf life isopropyl ester PMR technology versus the traditional methyl ester PMR approach
Authors: Alston William B. , Scheiman Daniel A. , Sivko Gloria S.
Published: January 2006

Polymerization of monomeric reactants (PMR) monomer solutions and carbon cloth prepregs of PMR II‐50 and VCAP‐75 were prepared using both the traditional limited shelf life methanol based PMR approach and a novel extended shelf life isopropanol based PMR approach. The methyl ester and isopropyl ester based PMR monomer solutions and PMR prepregs were aged for up to 4 years at freezer and room temperatures. The aging products formed were monitored using high pressure liquid chromatography (HPLC). The composite processing flow characteristics and volatile contents of the aged prepregs were correlated versus room temperature storage time. Composite processing cycles were developed and six‐ply cloth laminates were fabricated with prepregs after various extended room temperature storage times. The composites were then evaluated for glass transition temperature (Tg), thermal decomposition temperature (Td), initial flexural strength (FS), and modulus (FM), long term (1000 h at 316°C) thermal oxidative stability (TOS), and retention of FS and FM after 1000 h aging at 316°C. The results for each ester system were comparable. Freezer storage was found to prevent the formation of aging products for both ester systems. Room temperature storage of the novel isopropyl ester system increased PMR monomer solution and PMR prepreg shelf life by at least an order of magnitude, while maintaining composite thermal and mechanical properties. © 2006 Wiley Periodicals, Inc.

A simple method for estimating parameters representing macroporosity of porous styrene–divinylbenzene copolymers
Authors: Malik Muhammad Arif , Ali Syed Wasim , Waseem Shabana
Published: January 2006

A quick, easy, and novel method to estimate pore volume (PV), pore size distribution, surface area (SA), and swelling coefficient in acetone (SCa) of porous styrene–divinylbenzene copolymer beads on the basis of their density (d) in dry state is developed. The density is determined by measuring cylinder method. The equation to calculate the parameters are 11.993 d2 − 14.04 d + 4.2 for PV, 68.449 ln(PV) + 208.08 for SA, and 136.47 e−1.8323(PV) for SCa. Regression analysis shows a close match between the estimated values and the corresponding values measured by mercury porosimetry, with square of the Pearson product moment correlation coefficient through data points in known y's and known x's (R2) values in the range of 0.93–0.99. The pore size distribution can be estimated from the given curves for the corresponding pore volume value. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 99: 3565–3570, 2006

Authors: Kozlov G. V. , Dolbin I. V. , Zaikov G. E.
Published: January 2006

The applicability of fractal analysis for a quantitative description of a structure of a macromolecular coil of branched polymers is shown. The important aspect of the offered treatment is a type of interaction between macromolecule elements (repulsion or attraction). One of the more important factors was the structure of this macromolecule characterized by its fractal dimension. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 99: 3574–3577, 2006
Friction and wear behavior of proton‐implanted phenolphthalein poly(ether sulfone)
Authors: Pei Xianqiang , Wang Qihua , Chen Jianmin
Published: January 2006

Blocks of phenolphthalein poly(ether sulfone) (PES‐C) were implanted with 110 keV protons in four doses: 1 × 1014, 5 × 1014, 2.5 × 1015, and 1.25 × 1016 ions/cm2. The structures of the pristine and implanted PES‐C blocks were characterized by FTIR–ATR and X‐ray photoelectron spectroscopy (XPS), whereas their friction and wear behavior were investigated with an M‐2000 friction and wear tester at room temperature in an ambient atmosphere. The results revealed that with an increased implantation dose, it took more time for the friction coefficient to become smaller and level off when the dose did not exceed 1016 ions/cm2. At the highest dose, 1.25 × 1016 ions/cm2, the friction coefficient started smaller but increased quickly and leveled off at a higher number. In addition, the wear rate first increased and then decreased. When the dose exceeded 1016 ions/cm2, the wear rate of the sample showed an obvious decrease. The FTIR–ATR spectra showed that partial degradation took place on the surface of PES‐C after proton implantation, and when the dose reached or exceeded 2.5 × 1015 ions/cm2, a new broad peak between 1600 and 1800 cm−1 appeared, showing that a carbon‐rich structure had formed on the sample surface. XPS analyses justified the FTIR–ATR results, including the formation of amorphous carbon and the partial degradation, which was responsible for the variety of friction and wear behaviors of PES‐C. © 2006 Wiley Periodicals, Inc.

Fungal degradation of wood‐plastic composites and evaluation using dynamic mechanical analysis
Authors: Schirp Anke , Wolcott Michael P.
Published: January 2006

Small samples of two wood–polyethylene (HDPE) composite formulations were incubated with either the white‐rot fungus Trametes versicolor or the brown‐rot fungus Gloeophyllum trabeum for 24 and 77 days in an agar‐block test. Noninoculated, side‐matched controls were employed in the tests to serve as references, and solid wood samples of yellow‐poplar (Liriodendron tulipifera L.) inoculated with T. versicolor were included as positive controls. Potential changes in storage and loss moduli because of fungal colonization and moisture were determined using dynamic mechanical analysis, whereas weight loss and visual observation served as indicators of fungal decay. Severe losses in storage modulus (E′) and loss modulus (E″) following incubation of yellow‐poplar with T. versicolor were observed. However, the E′ of the two wood–plastic composite (WPC) formulations increased after 24 days of incubation with T. versicolor. The same effect was observed for G. trabeum, but only in one formulation. The increase of E′ was attributed to a reinforcing effect of the fungal hyphae present in the interfacial gaps between the wood filler and the polymer matrix. Dynamic temperature scans revealed a peak in E″ between 30°C and 63°C, depending on the frequency and fungal treatment. The peak temperature of E″ represents the α‐transition of HDPE. Increased activation energies were required for the α‐transition in WPC samples incubated with T. versicolor for 77 days as compared to controls. This observation confirmed that incubation of WPC with T. versicolor improved interfacial adhesion and reinforced the composite under the assay conditions. © 2006 Wiley Periodicals, Inc.

Effect of hydrogen peroxide bleaching onto sulfonated jute fiber
Authors: Salam M. A.
Published: January 2006

Bleaching of raw and sulfonated jute fiber with hydrogen peroxide were carried out in an aqueous medium. To obtain the optimum condition for bleaching, the effects of hydrogen peroxide concentration, temperature, time, pH, and fiber–liquor ration were studied. Bleaching affected the whiteness and tenacity, and the optimum whiteness index (76) and tenacity (13.7 g/tex) for the bleached sulfonated jute fiber were obtained with 2.1% hydrogen peroxide at pH 11, temperature 95°C, treatment time 110 min, and fiber–liquor ratio 1 : 7. The photo‐oxidative degradation of bleached sulfonated jute fiber was characterized by UV light exposure and compared with that of bleached raw jute fiber. It has been observed that the photo‐oxidative degradation as well as loss in tenacity and yellowness of the bleached sulfonated jute fiber was 63 and 40% lower than that of bleached raw jute fiber. Bleached sulfonated jute fiber had excellent impact on color fastness with reactive dyes. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 99: 3603–3607, 2006
Self‐assembled poly(styrene‐co‐N‐isopropylacrylamide) film induced by capillary force
Authors: Deng Z. W. , Hu X. X. , Li L. , Xu Z. S. , Yi C. F.
Published: January 2006

The monodisperse poly(styrene‐co‐N‐isopropylacrylamide) (poly(St‐co‐NIPAAm)) particles prepared by emulsifier‐free emulsion polymerization with microwave irradiation were induced by capillary forces to self‐assemble, and formed the two‐dimensional films on the clean glassware wafer substrates. The morphologies of the two‐dimensional films were characterized by scanning electron microscopy (SEM) and atom force microscopy (AFM). The results showed that monodisperse poly(St‐co‐NIPAAm) particles could form ordered two‐dimensional films by capillary forces. With NIPAAm concentration increasing, there gradually appeared surface undulations or surface defective region on the two‐dimensional films. © 2006 Wiley Periodicals, Inc.

Preparation of micron‐size monodispersed PS/P(St/MAA) microspheres by seeded dispersion polymerization
Authors: Zhang Hong‐Tao , Huang He , Sun Rong , Huang Jin‐Xia
Published: January 2006

Uniform polystyrene (PSt) particles with the size of 1.9 μm were first prepared via dispersion polymerization, and then used as the seeds in a second‐stage dispersion copolymerization of styrene (St) and methacrylic acid (MAA) to produce carboxyl‐carrying microspheres. The PSt seed particles were swollen by monomer mixture of St and MAA, including an oil‐soluble initiator 2,2′‐azobisiso‐butyronitrile (AIBN), before polymerization. Finally, uniform PS/P(St/MAA) (polydispersity index, PDI = 1.02) microspheres with the size of 2.2 μm were obtained. The average particle size and size distribution of the final microspheres were investigated. MAA contents between 54 and 97 mg/g were detected from the PS/P(St/MAA) particles produced under different conditions. Dispersion medium has great influence on the kinetics of polymerization, due to its effect on the partitioning of monomers, solvents, and initiator in the particle phase, probably as well as on the conformation of the dispersion agent on the surface of the particles. © 2006 Wiley Periodicals, Inc.

Investigation of the reaction mechanism of different epoxy resins using a phosphorus‐based hardener
Authors: Varley Russell J. , Liu Weichang , Simon George P.
Published: January 2006

In this work, the fundamental kinetic and structure/property information for a novel phosphorus‐based hardener, bis(4‐aminophenoxy) phosphonate is cured with a range of common epoxy resins such as diglycidyl ether of bisphenol A, tri glycidyl p‐amino phenol and tetra glycidyl diamino diphenyl methane (TGDDM) at various cure temperatures. The rate coefficients k1 and k2 for the primary and secondary amine epoxide addition reactions, respectively, were determined and were found to exhibit a positive substitution effect for the TGAP and TGDDM epoxy resins. Etherification or internal cyclization were shown to be important at higher levels of cure conversion, with these reactions being more significant for the TGAP/BAPP system. Some basic structure/property relationships were established between the glass transition temperature (Tg) and epoxide conversion. The master curve obtained for the superimposition of the various cure temperatures for each epoxy demonstrated the independence of the cure mechanism with temperature. © 2006 Wiley Periodicals, Inc.

Radiation‐induced grafting of acrylic acid and sodium styrene sulfonate onto high‐density polyethylene membranes. I. Effect of grafting conditions
Authors: Zu Jianhua , Wu Minghong , Zhang Jianqiu , Yu Chunhui , Liu Xinwen , Tong Long
Published: January 2006

Radiation‐induced grafting of sodium styrene sulfonate and acrylic acid onto high‐density polyethylene (HDPE) membranes was studied by the preirradiation technique. Grafting was carried out using an electronic beam from a 2‐MeV accelerator at room temperature. The effects of the type of solvent, inhibitor concentration, preirradiation atmosphere, monomer concentration, and storage time of preirradiated HDPE membranes on the grafting yield were investigated. Easy control over the grafting yield was achieved by proper selection of the reaction conditions. IR spectroscopy analysis of the grafted membrane confirmed the existence of sulfonate and carboxylic acid groups in the grafted membranes. © 2006 Wiley Periodicals, Inc.

Preparation of core–shell glass bead/polysulfone microspheres with two‐step sol–gel process
Authors: Yujun Wang , Ying Xiong , Fei Chen , Guangsheng Luo
Published: January 2006

Core–shell microspheres made from glass beads as the core phase and polysulfone (PSf) as the shell phase can act as an absorbent in the separation process or a supporter for chemical reactions. Based on phase‐inversion principles, a two‐step sol–gel method was developed in this work in which ether was added first and H2O was added second to a PSf‐containing dimethyformamide (DMF) solution to help PSf solidify on the surface of glass beads. The results from scanning electron microscopy, Fourier transform IR, and X‐ray photoelectron spectroscopy showed that a dense layer of PSf (thin to several microns) was coated on the glass beads and the core–shell microspheres were almost monodispersed. The utilization percentages of the glass beads and PSf were high as 100 and 80%, respectively. The thickness of the PSf membrane was calculated to be about 4.3 μm. To obtain well‐monodispersed microspheres, the practical volume ratio of ether to DMF was recommended to be larger than 4.5. The results suggested that the two‐step sol–gel method is a highly efficient process for preparation of glass bead/PSf core–shell microspheres. © 2006 Wiley Periodicals, Inc.

Electrochemical properties of polypropylene membranes modified by the plasma polymerization coating of SO2/acetylene
Authors: Basarir F. , Choi E. Y. , Moon S. H. , Song K. C. , Yoon T. H.
Published: January 2006

Polypropylene membranes were modified by the plasma etching of SO2, SO2O2, or SO2H2O, followed by the plasma polymerization coating of SO2/acetylene. The conditions for SO2 plasma etching were optimized by the measurement of the ion‐exchange capacity (IEC) as a function of the plasma‐etching power (10–30 W), gas pressure (40–60 mTorr), and treatment time (15–120 s). For the plasma etching of SO2O2 and SO2H2O, only the pressure ratio (SO2/O2 and SO2/H2O) was optimized under the optimized conditions determined from SO2 plasma etching. Plasma etching was then combined with the plasma polymerization coating of SO2/acetylene, for which the conditions were again optimized by the measurement of the IEC as a function of the plasma power (10–40 W), chamber pressure (50–200 mTorr), SO2/acetylene ratio (15/135–60/90), and treatment time (0–10 min). Next, the electrical resistance and water uptake were evaluated. The modified membranes were also analyzed with scanning electron microscopy, whereas plasma polymer coatings were characterized with Fourier transform infrared/attenuated total reflection. © 2006 Wiley Periodicals, Inc.

Analysis of structural changes in bleached keratin fibers (black and white human hair) using Raman spectroscopy
Authors: Kuzuhara Akio
Published: January 2006

To investigate the influence of bleaching treatments on keratin fibers, the structure of cross‐sections at various depths of bleached human hair (black and white human hair) was directly analyzed without isolating the cuticle and cortex, using Raman spectroscopy. The S–S band intensity existing from the cuticle region to the center of cortex region of virgin white human hair decreased, while the S–O band intensity at 1040 cm−1, assigned to cysteic acid, increased by performing the bleaching treatment. Especially, the S–O band intensity of the cuticle region increased remarkably compared with that of the cortex region. Also, the amide III (unordered) band intensity in the cortex region increased, indicating that some of the proteins existing throughout the cortex region changed to the random coil form. Moreover, it has been found that the S–S band intensity existing from the cuticle region to the center of the cortex region of the virgin black human hair decreased remarkably, while the S–O band intensity increased significantly compared with that of the virgin white human hair by performing the bleaching treatment. From these experiments, we concluded that the melanin granules including metal ions act as a decomposition accelerator for the oxidizing agent, thereby leading to a higher level of disulfide (–SS–) group cleavage in the black human hair compared with that of the white human hair. © 2006 Wiley Periodicals, Inc.

Effect of diethylsulfoxide on the thermal denaturation of DNA
Authors: Markarian Shiraz A. , Asatryan Arpine M. , Grigoryan Karine R. , Sargsyan Hasmik R.
Published: January 2006

DNA thermal denaturation has been investigated in aqueous solutions of diethylsulfoxide (DESO) by means of UV‐vis and densimetry methods. It is suggested that, on the one hand, the structural change of entire solutions and, on the other hand, a direct interaction of DESO with DNA are responsible for the observed peculiar behavior. The results obtained were compared with those of dimethylsulfoxide (DMSO), also known from literature © 2006 Wiley Periodicals, Inc. Biopolymers 82: 1–5, 2006

Published: January 2006

Derivatives of naphthalene‐1,4,5,8‐tetracarboxylic acid with amidine structures have been prepared. The light absorption of the bisimide derivatives in the UV region is shifted to the visible for the amidine imides, which also fluoresce with a large Stokes shift. It has been shown how the bisimide–lactam rearrangement can be extended to amidine structures.
Nature of Base Stacking: Reference Quantum‐Chemical Stacking Energies in Ten Unique B‐DNA Base‐Pair Steps
Authors: Šponer Jiří , Jurečka Petr , Marchan Ivan , Luque F. Javier , Orozco Modesto , Hobza Pavel
Published: January 2006

Base‐stacking energies in ten unique B‐DNA base‐pair steps and some other arrangements were evaluated by the second‐order Møller–Plesset (MP2) method, complete basis set (CBS) extrapolation, and correction for triple (T) electron‐correlation contributions. The CBS(T) calculations were compared with decade‐old MP2/6‐31G*(0.25) reference data and AMBER force field. The new calculations show modest increases in stacking stabilization compared to the MP2/6‐31G*(0.25) data and surprisingly large sequence‐dependent variation of stacking energies. The absolute force‐field values are in better agreement with the new reference data, while relative discrepancies between quantum‐chemical (QM) and force‐field values increase modestly. Nevertheless, the force field provides good qualitative description of stacking, and there is no need to introduce additional pair‐additive electrostatic terms, such as distributed multipoles or out‐of‐plane charges. There is a rather surprising difference of about 0.1 Å between the vertical separation of base pairs predicted by quantum chemistry and derived from crystal structures. Evaluations of different local arrangements of the 5′‐CG‐3′ step indicate a sensitivity of the relative stacking energies to the level of calculation. Thus, describing quantitative relations between local DNA geometrical variations and stacking may be more complicated than usually assumed. The reference calculations are complemented by continuum‐solvent assessment of solvent‐screening effects.
