The technological and operational properties of press-materials based on novolak composition modified jointly by epoxydianic resin and polyvinylpyrrolidone aepending upon filier naturę and pressing conditions have been determined. The reactivity of obtained press-powders has been investigated depending upon fiUer type, as well as curing conditions of composites under which ammonia and formaldehyde are not emitted. It has been shown that developed press-materials have the same technological and operational properties compared with known phenoplasts but their heat resistance, impact strength and electroinsulating properties are better.
