Influence of temperature on the process of obtaining coumarone-indene-carbazole modifier of road oil bitumens

A narrow coumarone-indene fraction was obtained from liquid coal coking products. Based on this fraction and carbazole's presence, coumarone-indene-carbazole resin (CICR), a new type of kooligomers, was synthesized by ionic polymerization, which is proposed to be used as an adhesive modifier of road oil bitumens. The influence of temperature on the process of CICR synthesis, its quality, and characteristics of bitumen modified by it were studied.
