Mixtures of ethylene and oxygen dissolved in water under pressures ranging from 200 to 700 Ib./sq. in. were irradiated with Corn gamma rays at a dose rate of 180,000 r./hr. C values (molecules/100 ev.) for aldehyde production as high as 200 were observed. Increasing total pressure and dose were foun

The properties of poly(vinyl alcohol) (PVA) hydrogels containing saccharides (D-xylose, D-fructose, D-glucose, and maltose) were examined. The effect of the addition of saccharides to PVA hydrogels on their melting temperatures was remarkable when the gels were chilled at 0Β°C with saccharide content
## Abstract Reticulation of a dilute aqueous solution of poly(ethylene oxide) in a ^60^Co gammaradiation field yields a weak gel which is characterized by its damped sinusoidal oscillation in a freeβswinging torsion pendulum. A storage and a loss modulus are calculated from the log decrement and fr
