The work is devoted to high quality liquid pyrolysis products processing through their polymerization to form polymeric petroleum resins. Cyclo-, dicyclopentadiene fractions of liquid pyrolysis products of straight-run gasoline were used as raw material. The authors have synthesized polymeric petroleum resins using catalyst complex based on titanium monoalkohyterchloride Ti(OС3Н7)Cl3 and diethylaluminumchloride Al(C2H5)2Cl. Titanium monoalkohyterchloride was obtained by TiCl4 interacting with isopropanol in the mole ratio of 1:1. It has been ascertained that the use of the catalyst complex allows obtaining polymeric petroleum resins with the improved physical and chemical characteristics. The properties of films based on synthesized polymeric petroleum resins, as well as the operating characteristics of pigmented and oil-resin coatings were investigated. The paper demonstrates the possibility of using the film binders in the coatings industry, both individually and in different compositions.
