Abstract—The properties of polysulfone-modified epoxy binders, which are intrinsic for their high deforma-
tion characteristics, are given. The experimental results of the impact strength, bend strength, and glass transi-
tion 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.

Keywords: glass transition temperature, working temperature range, epoxy matrix, polysulfone, differential
