|Title:||Effect of the acrylic acid content on miscibility and mechanical properties of mixtures of poly[ethylene-co-(acrylic acid)] and poly(2-ethyl-2-oxazoline)|
|Abstract:||Austenitic stainless steel can be attack by localized corrosion in saline environments, such as seawater. TiN/Ti multilayers can improve the corrosion resistance of the stainless steel better than TiN monolayers, because the titanium layers improve the impermeability of TiN/Ti multilayers. In this work, 1.75-4.55 ?m thick layers were deposited on to grounded or -100 V biased substrates of 304 stainless steel substrates by reactive magnetron sputtering. The corrosion resistance of the layers was studied by means of potentiodynamic polarization in 0.5 M NaCl solutions. It was found that the pitting corrosion resistance was dependent on the bias and period number of the multilayers. " 2007 Elsevier B.V.

Katime, I.",,"2001",,"The miscibility behavior of blends of poly(2-ethyl-2-oxazoline) (PEOX) and poly[ethylene-co-(acrylic acid)] was studies as a function of the acrylic acid content with the help of differential scanning calorimetry (DSC), modulated DSC and dynamic mechanical thermal analysis (DMTA). Miscibility, ascertained by the existence of a single glass transition in the mixtures, is achieved only between the PEOX and the copolymers with a high acrytic acid content (20%). The other two polymer pairs are immiscible at all compositions. FTIR spectroscopy demonstrates that miscibility is enhanced by hydrogen bonding interactions between the amide groups of the PEOX and the carboxylic groups of the acrylic acid units in the copolymer. Tensile stress and compressive creep tests reveal that the 20 and the 40 wt.-% PEOX blends exhibit synergistic mechanical properties, i.e., better ultimate properties, smaller Young's moduli and higher creep compliances.
