Glass transition amorphous aqueous solutions

The results presented here illustrate the general feasibility of this technique. They relate primarily to the behavior of thermal and current noise in the glass transition (Tg) or melting (Tm) region of an amorphous (polystyrene) and a crystalline (HD-polyethylene (HDPE)) polymer rendered conductive by the addition of minor amounts of carbon black, and further they relate to the noise of aqueous solutions of certain polymers during Couette flow. Because of experimental diflBculties, noise measurements on solid polymers during deformation and flow have not yet produced useful results. 

When heated, the glass changed into LDA, and this behavior was the same as that of HDA. This suggested HDA made by the pressure-induced amorphization resembled the vitrified HDL [23]. The existence of the glass transition between HDA and HDL was also hinted from the analogy of the glass transitions of dilute LiCl-aqueous solutions under pressure [24].
