The effect of stirring speed on the rate of the persulfate-catalyzed polymerization of vinylidene chloride has been determined. It was found that the first-stage rate decreases with increasing stirring speed, that the second-stage rate increases with

The volume changes which a cellulose gel swollen with water undergoes on immersion in aqueous glycerol solutions containing from 10–80% glycerol have been studied. If the gel is considered from the standpoint of dry cellulose plus glycerol solution

The dynamic elastic modulus of cellophanes has been measured by use of the resonant frequency of a 2 × 60-mm. strip of film in longitudinal vibration. The niodulus was computed from the resonant frequency length of specinieii, and the cross-sectiona

The thermal decomposition of the C4, C6, and C8 polymethylene sulfones has been investigated at 275°C. under reduced pressure. The gaseous decomposition products, collected and identified by infrared and mass-spectrometer analysis, were found to con

We have developed a simple method which permits measurement of the rate of densification of the gel forming during the coagulation of viscose and in effect experimentally separates the coagulation process from the regeneration process. The method is

In seeking an explanation for the unusual kinetics observed in the persulfate-catalyzed emulsion polymerization of vinylidene chloride, the role of particle coalescence has been examined. A theory has been proposed and the predicted results have been

The interactions of cellulose with highly hygroscopic ethylenediamine and ethylene glycol and with the less hygroscopic tetramethylene sulfone have been determined. The measurements are based on the difference between the equilibrium vapor pressure o
