Measurements of compressive stress relaxation for molded polytetrafluoroethylene were carried out at different temperatures over the range 60-150ยฐC., a t 5ยฐC. increments under a small strain (less than 0.3y0). By the application of the so-called Ferry's reduction method, three master curvea were obt
## Abstract The solโgel transition of gelatin, measured by thermal analysis and viscosity measurement, was analyzed in terms of the change in hydration state of polymer molecules. A new thermodynamic model was proposed in which the effect of water potential is explicitly taken into account for the
The depression of the glass transition temperature by water was studied in a set of polyurethanes in which the soft segment consisted of polyethylene oxide (sample I ) or a block copolymer of poly (propylene oxide) terminated with poly (ethylene oxide) in various proportions (sample set 11). DSC mea
