Abstract

The effect of polysulfone PSF-150 on the impact strength of epoxy resin ED-20 in the temperature range from –60 to +20°C was studied. It was shown that the epoxy resin modified with polysulfone has increased impact strength and retains an advantage over the unmodified one in the entire range of test temperatures. The system with a phase structure containing a continuous phase of thermoplastic makes a significant contribution to increasing the impact strength of the modified matrix.
