A freely oscillating torsional pendulum has been used to measure the dynamic-mechanical loss of polymers through the softening temperature by encapsulating the polymer in a rigid matrix of cured phenolic resin. The method is illustrated with loss curves through the glass transition region of poly(vinyl chloride), polystyrene, a styrene–maleic anhydride copolymer, poly(phenylene oxide), and two binary alloys involving these polymers. The advantages and simplicity of the technique are emphasized.
