The inhibition of the corrosion of iron in neutral and alkaline solutions. I
Abstract The potentials at which iron is converted into anhydrous cubic oxide in certain inhibitive solutions have been measured and it has been shown that these potentials are more negative than the potentials acquired by unpolarised specimens immersed in the solutions for 3 days. It is suggested that when iron, carr…
Effects of gamma radiation on some physical properties of polytetrafluoroethylene resin
Abstract Effects of gamma radiation on the properties, such as melt viscosity, elastic modulus above the melting point, creep fracture time above the melting point, density, and the degree of crystallinity by x‐ray diffraction, of polytetrafluoroethylene resin were studied. When exposed to the radiation from a Co 60 g…
The effect of the sorption process on the dynamic rigidity modulus of the wool fiber
Abstract Using a torsion pendulum, measurements have been made of the dynamic modulus of rigidity of wool fibers during the process of sorbing or desorbing water (from the vapor phase). Anomalous behavior is observed, with low values of rigidity which cannot be accounted for in terms of equilibrium data. It appears th…
Crystallization kinetics of isotactic polypropylene
Abstract Crystallization kinetics of Hercules polypropylenes were studied between 133 and 155 ° C. using dilatometers. The crystallization rates of these samples became too rapid below 133 ° C. for accurate dilatometric measurements. One sample (A) was a commercial sample containing stabilizer and 9% extractable polym…

Studies on the orientation phenomena by fiber formation from polymer melts. Part I. Preliminary investigations on polycapronamide
Abstract The problem of the mechanism of macromolecule orientation occurring in the formation of fibers from polymer melts has been qualitatively analyzed. As a result of birefringence, x‐ray, and spinning stress investigations carried out on polycapronamide fibers, the main parameters determining orientation have bee…
Stereoregular Polymers. II. Polymerization of Alkenyltrimethylsilanes with Ziegler Catalyst
Abstract Vinyl-(I), allyl-(II), and 3-butenyl-trimethylsilane(III) were polymerized at 70°C in n-heptane with the heterogeneous catalyst of Ziegler’s type. The monomer I gave only a small yield of polymer, while the monomers II and III gave moderate amounts of polymers. The amorphous and crystalline polymers of these…

InAs1-xPx as a Thermoelectric Material
Measurements of the electrical conductivity σ, the thermal conductivity K, and the Seebeck coefficient (thermoelectric power) α, of InAs1−xPx have been made at high temperatures with x varying from 0 to 0.4. Between 450° and 800°C, the average thermoelectric figure of merit (z = α2σ/K) increases moderately with x for…

The dynamic mechanical properties of nylons
Abstract A study of the dynamic mechanical properties of a series of polyamide polymers and some related polymers has been made over a wide temperature range at about 100 cycles/sec. by means of a vibrating reed method. The character of the β dispersion of the polyamides occurring at about −40°C. is discussed in relat…
Ferroelectric Properties of Colemanite
The ferroelectric properties of the calcium borate mineral colemanite are investigated in the ferroelectric and paraelectric temperature regions. It is shown that Devonshire's phenomenological theory may be applied successfully to account for the experimental measurements of spontaneous polarization and electrical sus…
