Abstract : The present communication reports the thermomechanical spectra of a 'dried' form of 'BBB' polymer throughout the temperature range -180C to 600C at about 1 cps, points out problems in preparing solvent-free specimens with infusible polymer, and demonstrates application of the technique of torsional braid analysis in investigating thermally irreversible changes by examining thermohysteresis effects.
