Estimation of glass transition temperature of polysulfone-modified epoxy binders.

The properties of polysulfone-modified epoxy binders, which are intrinsic for their high deformation characteristics, are given. The experimental results of the impact strength, bend strength, and glass transition temperature are given. The procedure of the measurement of the temperature range, at which there is a glass transition, is given. It has been shown that the amount of the introduced polysulfone to the binder has a greater influence on the temperature range where the change of the glass transition temperature occurs rather than its mean value.
